How to Use Audacity for Podcast Recording: A Step-by-Step Guide

Audacity is the most widely used free audio editor for podcasters, and for good reason. Whether you are recording your first episode or tightening up an existing workflow, this guide walks you through every stage from configuring settings before you hit record to exporting a loudness-normalized MP3 that meets platform standards. Follow the steps in order and you will avoid the most common mistakes that hold beginner podcasters back.

How to Use Audacity for Podcast Recording: A Step-by-Step Guide

Why Audacity Works Well for Podcast Recording

Audacity is free, open-source, and runs on Windows, Mac, and Linux. For podcast production, its feature set covers everything most shows actually need: multi-track recording, a noise reduction tool, EQ and compression effects, and a loudness normalization export path. It also uses a non-destructive editing model, meaning your original recorded audio stays intact until you explicitly export.

Why Audacity Works Well for Podcast Recording

The honest trade-off is that Audacity’s interface is not modern or immediately intuitive, and its real-time remote guest recording capabilities are limited. However, for capturing, cleaning, and exporting voice audio on a zero budget, it remains one of the most practical tools available. This guide is designed to flatten that learning curve.

What You’ll Need Before You Open Audacity

Having the right gear and software in place before you record prevents most setup-related problems.

What You’ll Need Before You Open Audacity

Microphone: A USB microphone (such as an Audio-Technica AT2020USB+ or Blue Yeti) plugs directly into your computer and works immediately in Audacity. An XLR microphone requires an audio interface (such as a Focusrite Scarlett Solo) as an intermediary.
Headphones: Closed-back headphones are essential for monitoring your input level during recording without causing feedback.
A treated recording space: A quiet room with soft furnishings reduces the reverb and background noise that Audacity’s noise reduction has to work against later.
Wireless lavalier option: For interview-based or on-location shows, a wireless lavalier system like the Hollyland LARK MAX 2 captures guests internally at 48 kHz / 32-bit Float. Its built-in AI noise cancellation also reduces the editing work needed in Audacity afterward. Import the recorded files from the SD card or receiver into Audacity just as you would any standard audio file.
LAME encoder: Audacity requires the LAME MP3 encoder to export MP3 files. Current versions of Audacity (3.x) bundle LAME automatically, but older installations may require a separate download from the Audacity website.

Setting Up Audacity for Podcast Recording

Getting your settings right before recording is the single most important step. Wrong settings at this stage create problems that editing cannot fully fix.

Choosing the Right Audio Settings

Click the Audio Setup button (the one with the mic icon), then choose Audio Settings from the drop-down arrow. In the next screen, you can configure the following:

Sample Rate: 44,100 Hz — This is the standard for podcast delivery and matches the requirements of every major hosting platform. Recording at 48,000 Hz is also acceptable (particularly if your interface defaults to it), but 44.1 kHz is the safe, universal choice.
Project Sample Rate (bottom toolbar): 44,100 Hz — This must match your preference setting to avoid silent resampling between import and playback.
Default Sample Format: 32-bit float — Record and edit in 32-bit float. This gives you headroom during editing (compression, normalization) without introducing clipping artifacts. You will export to 16-bit or 24-bit at the final delivery stage.
Channels: Mono — Solo voice is almost always recorded and delivered in mono. Stereo doubles the file size with no audible benefit for a single speaker and can introduce phase issues on certain playback devices.

Selecting and Routing Your Microphone in Audacity

Click the Audio Setup toolbar dropdown at the top of the Audacity window (the microphone icon) and select your external microphone or audio interface as the recording input device.
Set the Output device to your headphones so you can monitor your audio without creating a feedback loop.

Click the recording meter to enable input monitoring, then speak at your normal podcast volume.

Adjust the input gain slider on your interface, or use Audacity’s input level control, so your voice peaks between -12 dBFS and -6 dBFS. Peaks above -6 dBFS risk clipping; peaks below -18 dBFS leave your audio unnecessarily quiet and force heavier processing in post.

Note: The most common setup mistake is leaving the input device set to the default system microphone (usually a built-in laptop mic) rather than the external device. Always verify the correct input source in the toolbar before you start recording.

Recording Your Podcast in Audacity

Recording a Solo Podcast Episode

Recording Your Podcast in Audacity

Create a new project via File > New and save it with a descriptive filename immediately.
Close all unnecessary applications to reduce CPU noise and prevent background system audio from being captured.
Run a 5-second test recording. Play it back with headphones and confirm clarity, correct input device, and an acceptable noise floor before committing to a full take.
Capture room tone before your episode begins. Record 3 to 5 seconds of complete silence in your recording environment. This sample is used during the noise reduction step in editing.

Press the red Record button (or press R) to begin your episode.
Use Punch and Roll for mistakes. If you stumble mid-sentence, pause and count to three silently. This creates a visible gap in the waveform for easy editing later. In Audacity 3.x, Punch and Roll (Shift + Record) lets you re-record over a mistake without stopping and restarting the entire session.
Leave 3 to 5 seconds of silence at the end of your recording before stopping to provide a clean edit point and additional noise profile material.
Label your takes using Edit > Labels > Add Label at Selection (Ctrl/Cmd + B) for easier navigation during longer edits.

Recording Multiple Tracks or Guests

Audacity can record multiple channels simultaneously if your audio interface provides them. Go to Edit > Preferences > Recording, enable Record on a new track, and set the number of channels to match your interface.

For remote guests, Audacity is not the right capture tool. Record your side locally in Audacity while your guest records theirs using a platform like Riverside or Zencastr, or a separate Audacity session on their own machine. They send you the audio file afterward and you import it via File > Import > Audio.

Sync tracks by having all participants clap once at the beginning and aligning the clap transients on the timeline.
Keep each speaker on a separate track so you can apply different EQ or noise reduction settings to each voice independently.

Editing Your Podcast Audio in Audacity

The order of the editing chain matters. Running steps out of sequence (for example, normalizing before compressing) can undo or diminish the effect of other processing steps. Follow the steps below in order every time.

Step 1 — Remove Background Noise

Select the 3 to 5 seconds of room tone you recorded before the episode started.
Go to Effect > Noise Removal and Repair > Noise Reduction and click Get Noise Profile. Audacity analyzes this silence to identify the background noise signature.

Select the entire track (Ctrl/Cmd + A).
Return to Effect > Noise Removal and Repair > Noise Reduction and apply with the following starting settings:

Noise Reduction: 12 to 18 dB
Sensitivity: 6
Frequency Smoothing: 3

Click OK and play back a section of the treated audio.

Note: If your voice sounds metallic, watery, or robotic after this step, the reduction amount is too aggressive. Undo (Ctrl/Cmd + Z), re-apply at 10 to 12 dB, or recapture the noise profile from a cleaner silence sample.

Step 2 — Apply a High-Pass Filter

Low-frequency rumble from HVAC systems, traffic, desk vibrations, and mic handling noise typically sits below 100 Hz. Removing this frequency range does not affect voice clarity but noticeably cleans up the overall audio.

Go to Effect > EQ & Filters > High Pass Filter and set: – Frequency: 80 to 100 Hz – Roll-off: 12 dB per octave

This single step can make a voice recording sound cleaner and more professional without any perceptible change to the natural tone of the speaker’s voice.

Step 3 — Compress the Dynamic Range

Compression reduces the volume difference between your loudest and quietest moments, making the episode easier to listen to without requiring constant volume adjustments from the listener.

Go to Effect > Compressor and apply the following starting settings:

Setting	Recommended Value
Threshold	-18 dB
Noise Floor	-40 dB
Ratio	3:1
Attack Time	0.20 seconds
Release Time	1.0 second
Make-up Gain	Enabled

These settings are intentionally conservative. They even out dynamic inconsistencies in speech without squashing the natural rhythm and energy of conversation. Enable Make-up Gain to 0 dB after compressing to maintain a consistent output level after the effect is applied.

Step 4 — Normalize to Podcast Loudness Standards

Podcast platforms measure loudness in LUFS (Loudness Units Full Scale) rather than simple peak levels. The major platform targets are:

Spotify Podcasts: -16 LUFS integrated
Apple Podcasts: -19 LUFS integrated
General recommendation: -16 LUFS for broad compatibility across platforms

Use Audacity’s dedicated Loudness Normalization effect rather than the basic Normalize effect, which only adjusts peaks and does not account for perceived loudness:

Select the full track (Ctrl/Cmd + A).
Go to Effect > Volume and Compression > Loudness Normalization.
Set Perceived Loudness (LUFS) to -16 LUFS.
Leave the RMS option unchecked.
Click OK.

After applying, check that no section clips above 0 dBFS. If clipping occurs, apply a Limiter (Effect > Limiter) with a ceiling of -1 dBTP as a final safety pass before exporting.

Step 5 — Remove Mistakes and Clean Up the Timeline

Use the Selection Tool (F1) to highlight unwanted sections such as filler words, false starts, long silences, and coughs, then press Delete.
For pauses you want to shorten rather than remove entirely, use Effect > Truncate Silence to automatically collapse gaps longer than a defined threshold.
Add Labels (Ctrl/Cmd + B) at chapter points or segment transitions to make navigation faster in longer episodes.
Zoom in using Ctrl/Cmd + scroll wheel to make precise cuts around individual words without accidentally clipping the start or end of adjacent audio.

Exporting Your Podcast from Audacity

Once editing is complete, export the final audio file. Do not close the project before completing this step.

Go to File > Export > Export as MP3.
In the export settings dialog, set:

Bit Rate Mode: Constant
Quality: 128 kbps for voice-only episodes; 192 kbps if your episode includes music, sound effects, or a produced intro and outro

The Edit Metadata Tags window will appear next. Fill in the following ID3 fields:

Title: Episode name
Artist: Host name or podcast name
Album: Podcast series name
Track Number: Episode number
Year: Publication year

Click Save. Audacity uses the LAME encoder to generate the MP3 file.
Export a WAV backup as well via File > Export > Export as WAV at 24-bit if your podcast distributor accepts uncompressed audio or handles encoding on their end.
Save your Audacity project file (.aup3) via File > Save Project. The .aup3 file preserves your complete edit history and allows you to return to make future changes without starting from the raw recording.

Common Audacity Podcast Recording Mistakes to Avoid

Recording in stereo for a solo voice: Doubles the file size with no audio benefit and can cause phase issues on headphones. Fix: Set channels to Mono before recording.
Skipping the noise profile step: Applying noise reduction without a proper profile produces random artifacts across the audio. Fix: Always record 3 to 5 seconds of silence before the episode begins.
Normalizing before compressing: This reversal makes compression settings unpredictable and can introduce new peaks after normalization. Fix: Always compress first, then normalize.
Not monitoring with headphones: Listening through speakers lets room reflections mask input problems you will only discover during editing. Fix: Use closed-back headphones throughout recording and editing.
Deleting the .aup3 project file after export: If you need to make a correction later, you are forced to edit a degraded and already-compressed MP3. Fix: Archive the .aup3 file and raw WAV exports in the same folder as each episode’s MP3.
Recording at too low a gain: A quiet signal requires heavy amplification in post, which raises the noise floor alongside the voice. Fix: Target -12 dBFS to -6 dBFS peaks during recording.

Common Audacity Podcast Recording Mistakes to Avoid

FAQ

Q: Is Audacity good enough for professional podcast recording?

Yes, with the right setup. Audacity can produce broadcast-quality audio when paired with a suitable microphone, a treated recording space, and the editing chain covered in this guide. The software itself is rarely the limiting factor. Output quality depends far more on mic placement and room acoustics than on which DAW is used to edit the file.

Q: What audio format should I export my podcast in with Audacity?

Export as MP3 at 128 kbps for voice-only shows, or 192 kbps if your episode includes music or produced audio elements. Use a constant bit rate for consistent file sizes across episodes. If your hosting distributor requests uncompressed audio, export as a 24-bit WAV file and let the distributor handle encoding to their preferred delivery spec.

Q: Can Audacity record multiple guests at the same time?

Audacity can record multiple channels simultaneously if your audio interface supports it, but it is not designed for remote multi-guest recording. For remote interviews, use a dedicated platform like Riverside or Zencastr to capture each participant locally at high quality. Import those separate audio files into Audacity afterward for editing and mixing.

Q: What LUFS should my podcast be in Audacity?

Target -16 LUFS integrated for broad compatibility across platforms. Use Audacity’s Loudness Normalization effect (Effect > Loudness Normalization) and set the target to -16 LUFS. If you publish exclusively to Apple Podcasts, -19 LUFS is also acceptable, but -16 LUFS is the safer default for multi-platform distribution.

Q: Why does my voice sound robotic after noise reduction in Audacity?

This is caused by over-applying the noise reduction effect. The most common causes are a Noise Reduction value above 18 dB or a noise profile captured from a sample that included voice bleed rather than pure silence. Undo the effect, recapture your noise profile from a truly quiet 3-second sample, and re-apply at 10 to 12 dB.

Conclusion

The Audacity podcast workflow follows a consistent path: configure your settings before recording, capture clean audio with proper gain staging, then apply noise reduction, high-pass filtering, compression, and loudness normalization in that order before exporting. Getting the recording right at the source reduces the time you spend fixing problems in post. Run through this process a few times and it becomes a reliable, repeatable system.
