Making an MP3 that still sounds like the mix
Bitrate and what it costs you
MP3 export here is fixed at 320 kbps constant bitrate, the top of the MPEG spec, so the artefacts stay below what matters on a review copy. Lower bitrates smear cymbals, room tone and sibilance, which shows on a dialogue mix sooner than people expect.
Export from the master, once
Always encode from the uncompressed master rather than from another MP3. One encode is a compromise you control; two stacked encodes is a compromise you inherit.

Your audio stays on your device
Decoding, processing and export all run in your browser: compressed formats are decoded with the Web Audio API, and WAV, AIFF and MP3 files are written by JavaScript in the page. Your audio is never uploaded to our servers. Only anonymous page analytics and, if you sign in, your account and payment details go online.
Frequently asked questions
- Why convert a WAV to MP3?
- To send a review copy. A 24 bit 48 kHz WAV of a full scene is hundreds of megabytes; the same thing in MP3 fits in an email.
- What bitrate does the MP3 use?
- A fixed 320 kbps, the highest rate the MPEG spec allows, so a review copy stays clean on dialogue and room tone. Keep the WAV as the master either way.
- Can I change the sample rate at the same time?
- Yes. Sample rate, bit depth and format are all set before export, so a 96 kHz master can leave as a 48 kHz MP3.
- Is my master uploaded?
- No. The encode runs in your browser and the MP3 is written straight to your downloads folder.
