Convert

WAV to MP3

Convert WAV audio to MP3. You are starting from WAV, which is uncompressed PCM: perfect fidelity at roughly 10MB per minute. MP3 is the safe default: every player built in the last 25 years reads it. WAV is lossless and MP3 is lossy, so this discards audio data in exchange for a much smaller file. Runs on your own Vistalyth Tools instance. Files never reach a third party.

Features

  • Bitrate and sample rate control
  • Tags, artwork, and track metadata carried across wherever MP3 supports them
  • Batch conversion across a whole library
  • Your WAV files are processed on your own server and never uploaded anywhere

What you can do

  • Get a WAV file playing on a car stereo, an old phone, or anything stubborn
  • Standardise a mixed music or voice library on a single format
  • Meet an upload requirement that names MP3 specifically

Self-hosted. Your files never leave your network.

Vistalyth Tools runs entirely on your own infrastructure. Files processed with WAV to MP3 are never uploaded to third-party servers. Deploy a single Docker container and process files with full privacy, no watermarks, and no usage limits. Open source under AGPL-3.0.

Frequently asked questions

Will WAV to MP3 lose quality?
Some, unavoidably. Pick a bitrate you are happy to live with, because the discarded detail is gone for good and re-encoding upward later recovers nothing.
Are tags and cover art kept?
Yes, wherever the target has somewhere to put them. MP3 carries the common fields; anything exotic in the source may not survive.
Anything peculiar about WAV I should know?
WAV has no standard tag block, so artist and title fields most likely do not exist in the source to carry over.
Can I convert a whole folder at once?
Yes. Batch conversion applies the same settings to every file and returns them together.
