Simple tools for reading and writing WAV and raw audio files. Written in pure Dart, with no dependencies.
This package currently supports reading and writing 8/16/24/32 bit PCM, and 32/64 bit float formats. Other formats can be added as needed (just file a bug).
This package also supports WAVE_FORMAT_EXTENSIBLE, but only for reading. Extensible WAVs are essentially treated as ordinary WAV files, because wValidBitsPerSample and dwChannelMask are ignored. Please file a bug if you have a use case for either of these metadata fields, or for writing extensible WAV files.
// Read a WAV file.
final wav = await Wav.readFile(filename);
// Look at its metadata.
print(wav.format);
print(wav.samplesPerSecond);
// Mess with its audio data.
for (final chan in wav.channels) {
for (int i = 0; i < chan.length; ++i) {
chan[i] /= 2; // Decrease the volume.
}
}
// Write to another WAV file.
await wav.writeFile(otherFilename);
