The 'data' subchunk contains the size of the data and the actual sound:ДЈ6 4 Subchunk2ID Contains the letters 'data'Д¤0 4 Subchunk2Size = NumSamples * NumChannels * BitsPerSample/8 The number of bytes for one sample includingДЈ4 2 BitsPerSample 8 bits = 8, 16 bits = 16, etc.Дў ExtraParamSize if PCM, then doesn't exist Linear quantization)Дў2 2 NumChannels Mono = 1, Stereo = 2, etc.Дў8 4 ByteRate = SampleRate * NumChannels * BitsPerSample/8ДЈ2 2 BlockAlign = NumChannels * BitsPerSample/8 Rest of the Subchunk which follows this number.Дў0 2 AudioFormat PCM = 1 (i.e. The 'fmt ' subchunk describes the sound data's format:ДЎ2 4 Subchunk1ID Contains the letters 'fmt 'ДЎ6 4 Subchunk1Size 16 for PCM. The 'WAVE' format consists of two subchunks: 'fmt ' and 'data': This is the size of theД®ntire file in bytes minus 8 bytes for the This is the size of the rest of the chunkДЇollowing this number. The canonical WAVE format starts with the RIFF header:Д 4 ChunkID Contains the letters 'RIFF' in ASCII formД¤ 4 ChunkSize 36 + SubChunk2Size, or more precisely:Д¤ + (8 + SubChunk1Size) + (8 + SubChunk2Size) I use the standard WAVE format as created by the MSDN (mostly describes the non-PCM, or registered proprietary To spend a week looking over it can be found at An almostД¬omplete description which seems totally useless unless you want Of two sub-chunks - a 'fmt ' chunk specifying the data format andДЄ 'data' chunk containing the actual sample data. Is often just a RIFF file with a single 'WAVE' chunk which consists A RIFF file starts out withДЄ file header followed by a sequence of data chunks. The WAVE file format is a subset of Microsoft's RIFF specificationДЇor the storage of multimedia files. Microsoft WAVE soundfile format WAVE PCM soundfile format
