Methods

appendFileContents(List<int> fileContents, {bool findDataChunk = true}) → void

Append fileContents read as bytes to our wave file. If findDataChunk is true, searches first to find the file's data chunk. It's recommended to call getDataChunk on the file contents you want to append first, to prevent repeating everytime you add the same file.

appendSilence(int msLength, WaveBuilderSilenceType silenceType) → void

Append msLength milliseconds of silence to our wave file. silenceType determines whether we start the counter for silence from the beginning of the last sample or the end.

getDataChunk(List<int> fileContents) → List<int>

Find data chunk content after <data|size> in fileContents

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

toString() → String

A string representation of this object.
