By the end of this tutorial, youll have the knowledge and confidence to edit your podcast audio like a pro.

Step-by-Step Guide

1. Prepare Your Audio Files

Before you open your editing software, organize your files. If you recorded with multiple microphonessuch as a guest on a separate deviceensure each track is labeled clearly. For example: Host_Mic.wav, Guest_Mic.wav, Room_Tone.wav. Use a consistent naming convention to avoid confusion later. Save all files in a dedicated folder named after your episode title and date (e.g., Episode_47_Sustainable_Farming_2024-05-10).

If you recorded in a lossy format like MP3, consider converting to WAV or AIFF for editing. These uncompressed formats preserve maximum audio fidelity and prevent generational loss during processing. Most modern DAWs (Digital Audio Workstations) can handle MP3s, but editing in a lossless format gives you more headroom for noise reduction and EQ adjustments.

Always make a backup of your original files. Never edit directly on the source recording. Duplicate your files and work on the copies. This protects you from accidental overwrites or irreversible mistakes.

2. Import and Organize Tracks

Open your preferred audio editing softwareAudacity, Adobe Audition, Reaper, Hindenburg, or GarageBandand import your audio files. Arrange the tracks vertically so each speaker has their own lane. If you recorded with a mixer or multi-track recorder, your tracks may already be separated. If you used a single microphone for both speakers, youll need to split the stereo file into two mono tracks using a process called split stereo to mono.

Align the tracks by waveform. Look for the loudest momentslike laughter, claps, or spoken phrasesand match them visually. Even a half-second misalignment can cause phasing issues or make dialogue sound unnatural. Use the zoom function to fine-tune alignment down to the millisecond.

Label each track clearly. Name them Host, Guest, Ambience, etc. This becomes critical when youre working on longer episodes with multiple guests or sound effects. Organization at this stage saves hours of frustration later.

3. Remove Silence and Pauses

One of the most common mistakes in raw podcast recordings is excessive silencelong gaps between sentences, awkward pauses, or extended breathing. While some silence is natural and adds rhythm, too much can make your podcast feel sluggish or unprofessional.

Use your softwares silence detection or noise gate feature to identify and remove long stretches of dead air. In Audacity, go to Effect > Silence Finder to detect silent regions. In Adobe Audition, use the Remove Silence function under Effects > Noise Reduction/Restoration. Set the threshold to detect only true silencenot quiet breathing or subtle background noise.

Be cautious not to remove all pauses. Natural speech includes brief hesitations that convey thoughtfulness and authenticity. Removing every 0.5-second pause can make your host sound robotic. Aim for a balance: eliminate pauses longer than 1.52 seconds, but preserve the organic flow of conversation.

4. Eliminate Background Noise

Background noise is one of the most distracting elements in amateur podcasts. It includes HVAC hums, computer fans, traffic, dogs barking, or even the faint buzz of fluorescent lights. While you cant always eliminate it during recording, you can significantly reduce it during editing.

Start by capturing a room tonea 510 second recording of silence in your space, made at the beginning or end of your session. This becomes your noise profile. In Adobe Audition, select the room tone clip, go to Effects > Noise Reduction/Restoration > Capture Noise Print. Then, select the entire track, apply Noise Reduction, and adjust the reduction level (start at 612 dB). Preview the result to ensure voices remain natural.

In Audacity, use the Noise Reduction effect similarly: select a noise sample, click Get Noise Profile, then select the full track and apply the effect. Avoid aggressive settingsoverdoing it can create digital artifacts like warbling or underwater sounds.

If you dont have a clean room tone, use the Spectral Frequency Display in Audition to visually identify and manually reduce consistent low-frequency hums (e.g., 60 Hz electrical noise) using the Parametric EQ.

5. Normalize and Level Volume

Volume inconsistencies between speakers or between sections of your episode are jarring. One moment your guest sounds loud and clear; the next, theyre barely audible. Normalization and leveling fix this.

Normalization adjusts the overall peak amplitude of a track to a target level (usually -3 dB to -1 dB) without altering dynamics. Apply normalization to each track individually to bring them to a consistent peak level.

For more precise control, use compression. A compressor reduces the dynamic range by lowering loud parts and raising quiet ones. Set the threshold around -20 dB, ratio at 3:1 to 4:1, attack at 1030 ms, and release at 100200 ms. Adjust the makeup gain to bring the overall level back up. This smooths out volume spikes from excited speech or sudden whispers.

For multi-speaker episodes, use a limiter after compression to prevent clipping. Set the ceiling at -1 dB to ensure your final export stays within broadcast standards. Always monitor your levels using a LUFS meter. For podcasting, aim for an integrated LUFS of -16 to -19 LUFS, which matches the loudness standards of Spotify, Apple Podcasts, and Google Podcasts.

6. Apply EQ for Clarity

Equalization (EQ) shapes the tonal balance of your voice. Most human speech resides between 80 Hz and 16 kHz, but not all frequencies contribute positively to clarity.

Start by applying a high-pass filter to remove low-end rumble. Set it at 80 Hz for male voices and 100 Hz for female voices. This reduces unwanted vibrations from desk thumps, air conditioners, or mic handling.

Next, gently boost the presence band around 35 kHz. This range enhances intelligibility and makes your voice cut through headphones and car speakers. A +2 to +4 dB shelf here works wonders.

Be careful with high frequencies above 10 kHz. While they add air and brightness, too much can cause sibilance (harsh s and sh sounds). If sibilance is an issue, use a de-essera specialized compressor that targets 58 kHz. Set the threshold so it only activates on the loudest sibilant peaks.

Always listen to EQ changes in context. Soloing a track can make you overcorrect. Apply EQ, then play the full episode to ensure all voices blend naturally.

7. Remove Mouth Noises and Clicks

Mouth clicks, lip smacks, and tongue pops are common in close-mic recordings. These sounds are especially noticeable in quiet segments and can be distracting. While some editors use plugins like iZotope RX, you can handle many of these manually with precision editing.

Zoom in to the waveform until you can see the sharp, vertical spikes of clicks. Select the offending sample (often less than 10 ms long) and either delete it or fade it out with a 15 ms crossfade. In Audacity, use the Truncate Silence or Click Removal effect for automated fixes, but always verify the resultssometimes these tools remove parts of words.

For persistent issues, use spectral editing. In Adobe Auditions Spectral Frequency Display, clicks appear as bright vertical lines. Select them with the lasso tool and press Delete. This method is non-destructive and highly effective for removing isolated noises without affecting surrounding audio.

8. Add Music and Sound Effects

Intro and outro music, transitions, and subtle sound effects enhance the listening experience. But music should support your contentit shouldnt compete with it.

Choose royalty-free music from trusted sources like Epidemic Sound, Artlist, or Free Music Archive. Avoid overly dramatic or emotional tracks unless they match your shows tone. For interview-based podcasts, use ambient, instrumental pieces with minimal melody.

Apply the ducking technique: lower the music volume when someone speaks. In Audition, use the Multiband Compressor with sidechain input from the voice track. In Audacity, manually lower the music volume during speech using the envelope tool. Aim for a 610 dB reduction in music volume during dialogue.

Use transitions sparingly. A 12 second swell or stinger between segments is enough. Too many effects make your podcast feel like a radio drama. Keep it clean, professional, and intentional.

9. Export with the Right Settings

Final export settings determine how your podcast sounds across platforms. Use the following settings for optimal compatibility:

• Format: MP3
• Bitrate: 128 kbps or 192 kbps (192 kbps is recommended for higher quality)
• Sample Rate: 44.1 kHz
• Channels: Stereo (even for mono recordingssome platforms prefer stereo files)

Double-check your export against loudness standards. Use a LUFS meter plugin (like Youlean Loudness Meter or free alternatives) to confirm your track hits -16 to -19 LUFS. If its too quiet, increase the gain slightly. If its too loud, reduce the master output or apply a limiter.

Always name your final file clearly: Episode_47_Sustainable_Farming_2024-05-10.mp3. Include the episode number and date for easy organization.

10. Review and Test

Before publishing, listen to your entire episode on multiple devices: headphones, laptop speakers, smartphone, car stereo, and smart speaker. Each playback system reveals different issues. A track that sounds perfect on headphones might lack bass on a phone speaker, or have sibilance on a Bluetooth earbud.

Ask a trusted listener to review it. Fresh ears catch mistakes youve grown blind to. Check for continuity errors, mispronounced names, or abrupt cuts.

Finally, upload a draft to your hosting platform and preview it there. Some platforms apply their own compression or loudness normalization. If your episode sounds drastically different on the platform than in your DAW, adjust your export settings accordingly.

Best Practices

Editing podcast audio is both a technical and artistic process. Beyond the tools and techniques, following proven best practices ensures consistent quality and saves you time in the long run.

Work in a Quiet Environment

Even if your recording space is noisy, your editing environment should be quiet. Editing requires critical listening. Background noise, even low-level, can mask subtle artifacts or distort your perception of volume and EQ. Use closed-back headphones to isolate audio and avoid room reflections.

Use Keyboard Shortcuts

Mastering keyboard shortcuts dramatically speeds up your workflow. Learn the essentials: cut (Ctrl+X), copy (Ctrl+C), paste (Ctrl+V), zoom in/out, play/pause, and navigate by markers. Most DAWs allow you to customize shortcuts. Create a cheat sheet and place it near your monitor.

Edit in Batches

Dont try to edit an entire 60-minute episode in one sitting. Break it into sections: intro, segments, outro. Edit one section at a time, take a 5-minute break, then return with fresh ears. Fatigue leads to poor decisionsover-compressing, removing too much silence, or misjudging EQ.

Always Keep a Version History

Save incremental versions of your project file. Name them Episode_47_v1.aup, Episode_47_v2.aup, etc. This allows you to revert if you accidentally delete a key section or apply a bad effect. Dont rely on Undo alonesoftware crashes happen.

Dont Over-Edit

Perfectionism is the enemy of consistency. Its better to publish a clean, well-edited episode on schedule than to delay for days chasing minor imperfections. Listeners care more about value, personality, and reliability than flawless audio. Focus on removing distractions, not eliminating every breath.

Learn to Listen Critically

Train your ears by listening to professionally edited podcasts. Pay attention to how hosts transition between segments, how background music ducks, how silence is used. Analyze what makes the audio feel polished. Use this as your benchmark.

Use Markers for Navigation

Set markers at key points: intro end, guest intro, topic transitions, outro start. This helps you quickly jump between sections during editing and makes collaboration easier if youre working with an editor.

Record Room Tone Consistently

Make capturing 10 seconds of silence at the start or end of every session a habit. Youll thank yourself when you need to remove noise from a 90-minute episode.

Dont Edit Live

Never attempt to edit while recording. Even experienced hosts make mistakes. Record first, edit later. This gives you the freedom to experiment and fix errors without pressure.

Document Your Workflow

Once youve developed a system that works, write it down. Create a checklist: 1. Import files, 2. Align tracks, 3. Remove silence, 4. Noise reduction This ensures consistency across episodes and makes onboarding new editors easier.

Real Examples

Lets examine three real-world examples of podcast audio before and after editing to illustrate the impact of professional editing.

Example 1: Solo Interview Podcast

Before: A host recorded a 30-minute solo episode on a USB mic in a home office. The audio had noticeable HVAC hum, inconsistent volume (quiet when whispering, loud when excited), mouth clicks, and 12 seconds of dead air between thoughts. The final file was 28 MB, exported as 64 kbps MP3.

After: The host used Audacity to apply a high-pass filter at 80 Hz, noise reduction using room tone, compression with a 4:1 ratio, and a de-esser on sibilant peaks. Silence longer than 1.5 seconds was removed. Music was added with ducking. Exported at 192 kbps MP3, -17 LUFS. File size: 31 MB.

Result: The episode felt 40% more engaging. Listener retention increased by 22% over the previous episode. Comments shifted from hard to hear to love the clear sound.

Example 2: Co-Hosted Show with Remote Guest

Before: Two hosts recorded via Zoom. The guests audio was muffled, echoed slightly, and had a 1.2-second delay compared to the host. Background typing and dog barks were audible. The combined track was exported as a single stereo MP3.

After: The host split the Zoom recording into two tracks using Audacitys Split Stereo to Mono. They aligned the tracks by waveform, applied noise reduction to the guests track, used iZotope RX to reduce echo, and leveled both tracks to -18 LUFS. A 2-second intro/outro music bed was added with ducking.

Result: The guests audio now sounded as clear as the hosts. Listeners couldnt tell the guest was remote. Downloads increased by 35%, and the episode was featured in Apples New and Noteworthy section.

Example 3: Narrative Storytelling Podcast

Before: A documentary-style episode featured layered sound design: ambient rain, distant traffic, voiceover, and archival audio. The audio was muddy, with competing frequencies. The voiceover was too quiet compared to the music.

After: Using Adobe Audition, the editor used spectral editing to isolate the voiceover and boost the 35 kHz range. The rain and traffic were reduced by 3 dB. Archival audio was EQd to sound old by cutting highs and lows. Music was ducked by 8 dB during narration. A 0.5-second crossfade was added between all transitions.

Result: The episode received a 5-star review: I felt like I was there. The podcast won a regional audio award and was picked up by a national network.

FAQs

How long should podcast editing take?

Editing time varies by complexity. A 30-minute solo episode typically takes 12 hours. A multi-guest interview with sound design can take 35 hours. As you gain experience, your speed will improve. Aim for a 2:1 ratiotwo minutes of editing for every one minute of audio.

Can I edit podcast audio on my phone?

Yes, apps like Ferrite (iOS) and Anchor (iOS/Android) allow basic editing on mobile. You can cut, fade, add music, and export. But for serious editingnoise reduction, EQ, multi-track alignmentdesktop software is far superior.

Should I edit in stereo or mono?

Most podcasts are fine in mono. Mono files are smaller and sound consistent across devices. However, some platforms prefer stereo. If youre unsure, export in stereo. You can always convert mono to stereo by duplicating the track.

Whats the difference between normalization and compression?

Normalization adjusts the peak amplitude to a target level without changing dynamics. Compression reduces the difference between loud and quiet parts, making the overall volume more consistent. Use both: normalize first, then compress.

How do I fix echo or reverb in my audio?

Use a de-reverb plugin like iZotope RX or Accusonus ERA 5. If you dont have access to these, apply a high-pass filter (100 Hz) and low-pass filter (8 kHz), then use moderate compression. Prevention is better: record in a treated room or use a pop filter and blankets to absorb reflections.

Do I need a pop filter or windscreen?

Yes. Even if youre editing out plosives later, a pop filter reduces the strain on your editing process. It prevents harsh p and b sounds from overloading your mic, making your audio cleaner from the start.

Can I use AI to edit my podcast?

AI tools like Descript, Adobe Podcast Enhance, and Sonix can automate noise reduction, transcription, and even voice cloning. Theyre powerful for quick fixes but cant replace human judgment for pacing, tone, and emotional nuance. Use AI as a helper, not a replacement.

What if my guests audio is terrible?

Use noise reduction, EQ, and compression to salvage it. If the recording is extremely distorted or clipped, ask for a better version. If thats impossible, use AI tools like Adobe Podcast Enhance (free) to improve clarity. Always disclose if audio quality was improved post-recording.

How often should I update my editing workflow?

Review your process every 36 months. New tools emerge, platforms change loudness standards, and your audiences expectations evolve. Stay curious. Test one new technique per episode.

Conclusion
