RIFF header & bit depth

[SonneKiwiBird]

Hi again.

Thank you as always.
While working on the raw stream of decoded audio file, I realized that

• RIFF header is not available.
• Bit depth conversion is not supported.

Am I understanding correctly? If this is correct, I may need to make one myself from the scratch. Then, I need to do some study...

Thank you.

I'm currently making a wave header writer. Let me see if I can contribute to your library.

I finished making one.
It creates 8 bit (sbyte[]), 16 bit (short[]) & 32 bit (float[]) wav header.
It also supports bit depth conversion.
If you are interested in this, I'd like to create a pull request. Before doing so, I'd like to make a design decision for your library style.
Where would it be the best place to put this?

I have thee exposed classees, one interface and 3 methods.
WaveData8bit, 16bit & 32bit with IWaveData.
Initalized like WaveDataNbit(dataArray[], sampleRate, channels)

Methods

1. WriteToBinaryWriter(BinaryWriter binaryWriter);
2. 2 conversion methods like 32bit to 8bit & 16bit.

Sorry for the late response, WASM support takes all my time.

While working on the raw stream of decoded audio file

Are you attempting to play a raw stream using players like SoundPlayer? If so, consider using the RawDataProvider instead of the standard data providers, as it only requires the raw PCM stream and does not need headers or any additional information.

Thank you for your work. I would love to see more contributions to this library, but doesn't the MiniAudioEncoder already serve this purpose? Although it currently only supports WAV encoding (with no MP3 or OGG encoding capabilities), it does accept a file path, sample format (target bit depth), and sample rate and allows encoding via the public int Encode(Span<float> samples) method, and I can refactor it later to add support for streams and BinaryWriter.

Sorry for the late response from my side too.

The library I'm using now requires raw data stream which is short[] with the header information.
FYI, http://soundfile.sapp.org/doc/WaveFormat/

What I made can convert the bit rate of the pure sound data array and add the wave header accordingly.
If MiniAudioEncoder can generate this kind of wave header, my work is not needed.

In case what I made is still needed, please let me know. I'd like to contribute too.
