Audio Tools

5 tools tagged “audio”.

Convert audio files between MP3, WAV, OGG, FLAC and M4A. Drop in as many files as you like, pick the target format and bitrate, and download the results one by one or all at once.

See everything about an audio file: duration, format, codec, sample rate, bit depth, channels and bitrate, the embedded tags and cover art, plus measured peak and RMS levels and a waveform overview.

View and edit the ID3 tags of an MP3, including title, artist, album, year, genre, track number, lyrics and cover art. Reads the existing metadata of other audio formats too, and saves a tagged copy of your MP3.

Cut a section out of an audio file on a zoomable waveform timeline. Drag the start and end handles, play back just your selection, fade the edges if you like, and export the result as MP3, WAV, OGG, FLAC or M4A.

Translate text to Morse code and Morse back to text, with a reference table of every letter, digit and punctuation mark. Play any result as sound with adjustable speed and tone.
