wav to flac corruption
So some research and experimentation I think I found the problem, but I'm
not sure how to go about fixing it.
If I import one of the wav files into Audacity then export them as "16 bit
PCM" then they encode to flac and play fine. The files bitrates are
currently at 24. If I export them from audacity as a 24 or 32 (anything
higher than 16), flac fails on me. With a bitrate of 24, the

Wav to Ogg Vorbis conversion
Dear experts,
I am trying to use an example I found here:
http://svn.xiph.org/trunk/vorbis/examples/encoder_example.c
Could you please tell me what float** buffer is needed for (I don't see
it used anywhere).
Also, could you please tell me what this code is doing:
for(i=0;i<bytes/4;i++){
buffer[0][i]=((readbuffer[i*4+1]<<8)|

Well, it's possible to put compressed data into the WAV file instead of PCM
audio data, and set the compression-type format flag to some made-up value, but

someone out there knows more about this than me.

Wrong WAV AudioFormat
Hi,
I am using vorbis-tools 1.4.0 on Fedora 14 to convert Ogg Vorbis files
to MS WAV format. It seems that ogg123 is encoding the wrong AudioFormat
value. For Uncompressed PCM, the AudioFormat should be 1 but for some
reason, it is being encoded in the WAV file as -1.
This used to work on some prior version of either Fedora or
vorbis-tools. I thought I'd ask in the email list in case

Can you provide me with a copy of one of these files? Please

question about coding
Thanks for the answer.
So data are stored in little-endian format on the WAVE file. But have I to encode in big endian format or little endian is ok?!
Thanks

endian problems with AIFF and WAV
I have a test program that loads an AIFF or WAV file with libsndfile and
plays then using libao. After running around in circles for a while, I
found and fixed the problem, but I'm still confused as to why the solution
works. Would someone please explain this to me so I don't trip over this
again later in my project?

Encode wav to uncompressed flac
File size is not important for me. I need audio data from wav file and
metadata in one file. How to encode a wav file to an uncompressed flac file?

A-law and mu-law
Hi Martijn,
thank you for your answer. So the problem would be suboptimal
compression due to suboptimal assumption about the input signal, right?
What I do not understand is how the format of a FLAC format would be
affected by supporting A-law and mu-law files as input (and thus
output). Despite of suboptimal performance, is it possible to treat 8bit
*-law samples as 8bit linear PCM files and

warning that legacy WAVE file has format type 1 but bits-per-sample is 24
Hello,
I've tried encoding a FLAC file from a WAVE file saved with
24-bits-per-sample, using the flac executable. I get this warning:
WARNING: legacy WAVE file has format type 1 but bits-per-sample=24
The code is currently here on line 373:

[PATCH] for flac/decode.c
The commit http://git.xiph.org/?p=flac.git;a=commitdiff;h=99257e177eac96fa41a107b423080232f59ebe45
also requires some changes in write_iff_headers() function:
currently flac don't write WAVEFORMATEXTENSIBLE header if
decoder_session->channel_mask is equal to 0, 1 or 3.
After the commit 99257e17 flac should do this for channel_mask
equal to 0, 4 or 3.
The patch fixes this.

some report on type 3 wav
Dear all,
I have a wav file that when I try to encode with the FLAC Frontend, I
get "ERROR: unsupported format type 3".
When I open it with an audio editor I find it is 44100 / 32 bit. I
requantized it to 16 bit using the default dither and then compressed it
with FLAC to get a 61 Mbyte file (the original was about 347 Mbyte).
Obviously, this altered somewhat the quality, although

FLAC C API / Visual Studio 2008 FILE* Issue
I managed to get around it. I used the stream functions and provided my own
callbacks for reading and writing. What's strange is that what I've done is
just copied the contents of read/write/seek/tell/eof callbacks from the
sources to my application and it works just fine, no glitches. When I use
the build-in implementation, it just crashes without any reason. It's not a

I am currently learning the FLAC C API and had the code working with
