And if you are passing values to a function and are not really sure what they are you could just be passing zeros and therefore you get no error because you pass 0, 0, 0 as far as the function is concerned when it should be 3, 256, 90. Typically, the count in nChannels equals the number of bits set in dwChannelMask, but this is not necessarily so. Look back at the thread that Tom gave you a link to, i posted some code to show you the data for an extensible format. Then again, maybe I did read something like that but it just did not register until I started thinking about how the 3 bytes would be separated into different buffers. However, these two structures are nearly identical. There are 3 variants of the Format chunk for sampled data. In this case, buffer estimation and position information needs to be obtained in other ways.
In the wav file example I was trying to add two bytes for a short int32 and could not figure how to do it by hand. In its simplest form, it adds a chunk with additional metadata. I figured that maybe Reed or one of the other forum members that are familiar with this subject could help get it figured out. But we have a disagreement by Hitfilm here. I am posting the correct vb. You can't get 24 bit or me? With this background, it's unclear to me what you are asking for.
Some files do not seem to work with this process, but it's possible that the header can be tweaked to fix these. Might it be listed as 65534? For conversions, something like ffmpeg -i my32bitfile. Maximum rate in an audio frame is 3072000 bps. I have not had to do any repositioning of the data and don't think a 24 bit would either. Then again, maybe I did read something like that but it just did not register until I started thinking about how the 3 bytes would be separated into different buffers.
I am only using a 16 bit file right now, but I would think that I am simply parsing an extra byte and the math is based on 8. Where is the format of 'hex file' specified? I haven't taken any of this far enough to actually try playing any audio with these methods because it does look like a lot more interop code than just the wave structures. Programming, it's the new crack and i can't put the pipe down. I do think it should work once everything is specified correctly. The only thing i can think of is to read the 24bit wave data and convert the values into a 4 byte Integer. All the speaker and wformats are hex right? I am staying out now.

Maximum bit rate in an audio frame is 1536000 bps. I can't get the extensible at all. For example, if it is suppose to represent the ValidBitsPerSample for the 24bit pcm wave file but, it was named SamplesPerBlock, it would be confusing for the programmer to try to remember what that member of the structure really represents in their code. I have tried both denoting the other 2 variables leaving validbits as well as simply moving it into the structure. For more information, see the following Remarks section. A Ushort is 16 bit correct? Good job working it out! Set this member to zero if each block of compressed audio data contains a variable number of samples.
I wonder what happens when this number isn't an integer? Alternatively, the channel mask can be specified as one of the following constants, which are defined in Ksmedia. I know that 24bit wave data is read as 3 bytes which is the only difference between the 8bit, 16bit, and 32bit files that it will play. All numerical values are little endian. It is supposed to just use the default mapping for the number of channels currently provided, which is exactly what I thought would be required. Liked the post about fancy sound card.

Samples is a union whose other member, wValidSamplesPerBlock, is used instead of wValidBitsPerSample for some compressed formats. It does seem as though it should play the 24bit file if it plays the 32bit file though. However, if i read the data from a 24bit file it fills the structure in properly but, does nothing but make a scratchy garbled sound when i play it. The original header could already handle multiple channels but there was no way to define what channel went to which speaker. It might be since it is off the forum. Another field dwChannelMask contains bits which indicate the mapping from channels to loudspeaker positions.
Liked the post about fancy sound card. This parameter points to the structure at the beginning of a buffer that also contains a format descriptor. I am not so sure they can be used to play a 24bit format. The data is correctly represented in the precision of the container size. There is more to it than just offsetting the first byte x 256 or something. I found a page that has some of the sizing.
