Hello I am currently working on steganography and want to convert .wav file into raw binary dadta. but i don't know how to do that. Please do tell me if anybody knows it.

— WAV files are just a RIFF container with a header and a "data" chunk that contains the raw PCM samples you want. pointed to a code snippet and and suggested online converters; if you prefer a local, repeatable workflow for steganography, convert to raw PCM (no header) and operate on the sample bytes.

A quick Python approach (standard library) — this reads the frames exactly as stored and writes them out, so the output is the raw binary payload from the data chunk:

import wave

with wave.open('input.wav', 'rb') as w:
    nch = w.getnchannels()
    sw  = w.getsampwidth()
    fr  = w.getframerate()
    n   = w.getnframes()
    frames = w.readframes(n)

print(nch, sw, fr, n, 'bytes=', n * nch * sw)

with open('output.raw', 'wb') as out:
    out.write(frames)

If you want a command-line tool, ffmpeg converts back and forth reliably. Example: convert WAV to 16-bit little-endian raw PCM and back (adjust sample format, sample rate, and channels to match the original):

ffmpeg -i input.wav -f s16le -acodec pcm_s16le output.raw
ffmpeg -f s16le -ar 44100 -ac 2 -i output.raw -acodec pcm_s16le restored.wav

Cautions specific to steganography: confirm sample width and endianness (WAV uses little-endian; 8-bit is unsigned, 16-bit is signed), handle stereo interleaving, avoid lossy formats (MP3 will destroy hidden data), and include length/checksum metadata in your hidden payload so extraction knows when to stop. If the WAV uses compression or nonstandard chunks, decode to PCM first (ffmpeg can do this). Back up originals before testing.

I can't be sure, but I found this:
