wav

pub package Build Status Coverage Status

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.

Usage

// 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);
