How to enhance podcast audio
Open the episode
Drop your recording above, or record straight into the studio.
Choose the Podcast preset
Stronger noise removal, a little warmth and clarity, and firmer compression for a broadcast feel.
Export with the Podcast target
−16 LUFS, peaks under −1 dB, mono MP3. Ready to upload to your host.
Podcast noise and other problems it fixes
Quiet episode next to loud ads
Loudness on export puts every episode at the same level, so listeners stop reaching for the volume.
A buzzing room
Fridge hum, a laptop fan or the AC are turned down under your voice.
Breaths and room noise in pauses
The gate quiets the gaps between sentences.
Uneven delivery
The compressor lifts trailing words and tames sudden laughs.
Thin, boxy sound
The Podcast EQ adds body low down and air up top.
Clipped peaks
The limiter catches peaks before they distort.
Why −16 LUFS?
LUFS measures how loud audio sounds to people, not just how high the peaks go. Podcast apps play episodes back to back with other shows and ads, so a common target keeps everything at a similar level.
Around −16 LUFS is the level many podcast hosts and apps recommend. VoiceStudio measures your whole episode the way broadcast meters do (BS.1770), sets the gain to hit −16, and uses a limiter so peaks stay under −1 dB.
The Podcast export is mono at 44.1 kHz. A single voice does not need stereo, and mono needs half the data, so the file stays small.
What it will not do for your show
Mix several tracks
It works on one file at a time. For a remote interview, clean each person’s track, then mix them in your editor.
Make a bare room sound like a booth
It cuts room echo noticeably, but a bare, echoey room still shows. Blankets, a closet or a closer mic help more than any setting.
Write show notes
There are no transcripts, chapters or show notes.
Process a batch
Episodes are cleaned one at a time.
Questions
What is the best free podcast audio enhancer?
It depends on your recording. If noise and uneven levels are the problem, VoiceStudio fixes both for free with no limits. It also reduces room echo, and the Podcast preset cuts it most. For a very echoey room, a tool that regenerates the voice may go further.
Will the result meet Spotify and Apple Podcasts loudness?
The Podcast export targets −16 LUFS with peaks under −1 dB, a level widely recommended for podcasts. Your host may re-encode the file, which is normal.
Can I record my podcast here?
Yes, for solo shows. It records your mic losslessly and saves every few seconds. It does not record remote guests.
Should I export MP3 or WAV for my podcast host?
MP3 is what most hosts serve to listeners, and the Podcast target saves a 96 kbps mono MP3. Choose WAV if you still want to edit the file in another program.
Can it remove music under my voice?
No. Background music is treated like noise and gets damaged. Add your intro music after cleaning, in your editor.
Is there a free podcast noise remover that doesn’t upload my episode?
Yes. VoiceStudio cleans episodes in your browser with no limits, and unreleased episodes never leave your computer.
