Seek failure with very short files
Hi all, Thanks in advance for your help, and sorry for the slow reply. I've created a small OS X example project <https://drive.google.com/file/d/0B8vFUUth7NpvRFI0MmI2bVJNNEU/view?usp=sharing> that reproduces the issue. (I've run into the size limit for emails on this list so I've put it on Google Drive.) The program just initializes a libFLAC++ stream decoder for a given file

Seek failure with very short files
Hi, Thank you both for your replies. I will try to put together a repro case when I get a chance. In our case, we are recording audio directly into FLAC files, so they can end up with very short durations. Since I sent my first email, I have also seen this reproduce with longer files. Thanks, Luke On Mon, Nov 21, 2016 at 3:07 PM, Federico Miyara <fmiyara at fceia.unr.edu.ar> wrote:

Question from Argentina
Dear Friends, I am new to this mailing list. I am with the National University of Rosario, Argentina, and I am writing a book on software-based acoustical measurements, which includes a chapter on FLAC for archival and streaming purposes from an remote embedded system including a sensor. I would like to ask why the seekpoint information in the seek table metadata block reserves 64 bit for

Looking for users of --keep-foreign-metadata
I need uncorrupted metadata, as I use data in Base64 encoding in a long text tag for my music synchronized light show. Implemented now in .mp3 ID3 tags, I hope to extend to FLAC, but that only works if metadata is kept exactly in its original content.

identical audio but not identical unrecognized chunks
Dear all, I've converted a wav file to flac but during the process three wrnings were casted. One of them I recall, it said that a BEXT chunk is unrecognized and thus ignored. Wouldn't it be posible to keep the unrecognized information as is when decoding the file? In general the extra chunks are located before or after the audio content, and represents a tiny part of the whole

Seek failure with very short files
I was wondering when it would be useful to compress very short audio files. The answer may be when there are lots of files, for instance in the case of sound fonts, or a large collection of transients. Probably it would be better to compress the whole collection as a single large file obtained by juxtaposing the short clips, with cues or marks to separate the original files. May be this

Strange behaviour --UPDATE--
Dear All, I've sent yesterday this issue, but as it contained two screenshots, I'm not sure if it reached the list. I post it again with some updates. 1) I had encoded a WAV file three years ago. Examining the FLAC file with an HEX/text viewer, i find at the beginning, after some headers, it declares reference libFLAC 1.3.1 20141125. However, I'm pretty sure I didn't use that

FLAC 1.3.0 released
There are several links to Windows compiles in the Hydrogenaudio thread for FLAC 1.3.0 at http://www.hydrogenaudio.org/forums/index.php?showtopic=101082 . On Unices or Linuxes building from git should be straightforward enough, or you wait until the distributions/package maintainers catch up. Also, congratulations to the whole development team for reinvigorating FLAC! Christoph On

Port to SCO Openserver with PAM enabled
Hi all, I'm writing to you becuase I have compiled PAM in SCO (now Caldera) Openserver 5.0.x, and when I tried to use SSH with PAM enabled, y realized that OpenSSH depends on the user to exist en the /etc/passwd, and /etc/shadow databases, or equivalent ones (it uses getpw...() functions to determine validity of the user). In Linux, the simlpe solution is to use nsswitch, but it seems to hard

Using line spectral pairs for LPC quantization
Dear Stefan, In the paper "Improved Forward-Adaptive Prediction for MPEG-4 Audio Lossless Coding", a non-linear compander is applied to the parcor coefficients prior to quantization. This compander is designed in order to minimize quantization error, especially for magnitudes close to unity. If you determine the typical distribution of magnitudes of the LPC coefficients, you could
