AudioDataContainer class

Class that contain the streamed audio data.

The data receives a Uint8List whatever the format is. This raw data is stored into rawData and its format is the one used when initializing the recorder. This class also provide methods to convert the data to other formats based on the original recorder format. For example to convert to Int8List the data when the recorder is initialized with PCMFormat.f32le, you have to use toS8List method. Be aware that the conversion is compute expensive and should be avoided if possible initializing the recorder with the format desired.

When streaming with StreamingFormat.opus, rawData contains a length-prefixed Opus packet instead of PCM samples.
