For the simple “canonical” wave file format, this will generally be the size of the file minus 44 bytes for the header data, up to and including this field. The “data” subchunk contains the actual audio data: Standard format and the extensible format, generated using Audacity. Marshmallow was able to play back 24-bit PCM wave files using both the Wave files that don’t include these extra fields. Or more than 16 bits per sample, but it’s also possible to encounter such The MSDN docs recommend this format for files with more than two channels The first two bytes are the same as specified in format code, and the remainder should match 0x00, 0x00, 0x00, 0x00, 0x10, 0x00, 0x80, 0x00, 0x00, 0xaa, 0x00, 0x38, 0x9b, and 0x71. ![]() ![]() This specifies the assignment of channels to speaker positions.įor extended wave files, format will be set to 0xFFFE to indicate that it’s an extended wave file, with the actual format specified here as a GUID. For example, if this is set to 20 bits and bits per sample is set to 24 bits, then that means that 24 bits are being used to store the sample data, but the actual sample data should not exceed 20 bits of precision. For PCM files, this contains the valid bits for sample.
