...and SpeexEnc, I cannot get clear sound when I try to Get PCM Char buffer from the microphone Encode Char buffer using Speex Decode Speex Char buffer into PCM char buffer Play PCM char buffer using WaveOut The end-result is very distorted sound. I use the following PCM format: waveFormat.nChannels = 1; waveFormat.nSamplesPerSec = 8000; waveFormat.wBitsPerSample = 8; Once sound is aquired by the mic, I send it to Speex in a Char buffer. It looks something like this: Encode(char* inBuffer, DWORD bufferLength) ... float* input = new float[frameSize]; ZeroMemory(input, fra...

...eem like a trivial matter to you and other experts in the field, but believe me, there are a lot of programmers, whose posts I saw on the web, who tried to use WaveIn/WaveOut and Speex and failed. As I understand it, WaveIn just buffers audio data according to the bit rate specified. So, if we use waveFormat.wBitsPerSample = 8, then each Char of the audio buffer describes an audio sample using 8 bits. On the output side, WaveOut expects each Char to describe an 8-bit audio sample as well. If we deal with 16-bit samples, then two Chars would describe a sample, and so on. My question is on how to deal w...

...use I was interested in the issue, I decided to take a look at the oggenc source, and in fact, it is your .WAV reader that's wrong. More precisely: there are two version of the format chunk, one that's old and belongs to the original .WAV specification (the corresponding structure is called WAVEFORMAT in the win32 sdk and has 14 bytes, the variant you'll typically see in (PCM) wave files is called PCMWAVEFORMAT and has 16 bytes - the size that you expect the format chunk to be). But there's also a newer one, called WAVEFORMATEX, which was created to suit the requirements of non-PCM codec...

Hello, When a voice message is saved and e-mailed as a wav, the total time of the voice mail does not show up in, e.g., windows media player, why is this? I have only used wav49/wav: ; Use wav49 format for all voicemail messages format=wav49|gsm|wav Justin.

At the risk of throwing more fuel on the fire, I found the following document on the Microsoft website. It appears to be the file format counterpart to the API documentation presented by Chris Wolf. I'm not familiar with the WAVE format, so I'll let you guys interpret it (or tell me it is irrelevant): http://www.microsoft.com/HWDEV/audio/multichaud.htm [As an aside: Why does Microsoft

Thanks for the reply, I have just recently started looking at Ogg streaming and wasn't sure if there was yet another playlist file for them, glad there isn't personally! Are there any sites set up to stream Ogg? Sorry about the confusion I was reading another thread on the discussion of someone that was implementing an Ogg ACM. In that case a FACT chunk makes peoples lives easier. OK,

...t;legacy" WAVE file? Second, format type 1 What is that exactly? In the source code I see "format type" is referred to as "format tag", since the variable name is "wFormatTag". Is this what's referred to in this reference http://soundfile.sapp.org/doc/WaveFormat/ as AudioFormat There it says 1 for PCM Is there something about PCM format that implies either 8- or 16-bits-per-second? I'm new at this and trying to understand it. Can someone explain? Also, a related but more practical question: is there *any* way to create a 24- or 32-bits-per-s...

...this guy. The last thing someone confused about types should use is a union. Listen, whatever types you're using, you're just dealing with data in memory. For an array, it's just a big block of data in memory. You need to know how that data is stored in memory. For audio data, WAVEFORMATEX tells you that with its contents. Don't let types deceive you - focus on the format of the actual data. Know that Speex needs either floats or shorts, with a sample rate of 8000/16000/32000 samples per second, and that it's your responsibility to pass it data in this format. If the...
