Exact FLAC subset constraints
I think you've found a bug, Bart. flac 1.2.1 did not have any FLAC__format_blocksize_is_subset() function, so the source you're seeing in format.c must be new. If the format documentation you linked to is correct, then either the specifications are self-contradictory, or the code is not implementing the subset checks as described. My interpretation is that blocksize bits of 0110

are 588 sample frames subset or nonsubset?
Hi I am thinking of ripping albums to a single flac file with embedded cuesheet. As track and index points have to be on a 588 sample boundary due to the CD TOC standard working in 588 sample frames, I thought it may be beneficial to rip CDs with a blocksize of 588 samples. According to the format page on sourcefourge a stream is subset if "The blocksize bits in the frame header must be

question regarding compression %
Hi, For those of you who don't know, I now have an application on pocket pc using flac. Live2496 does realtime encoding while recording. Live2496 typically is used to record a digital source using the Core Sound PDAudio device. Links are now on the main flac page if you are interested in learning more. I have a question. We have run across a 24-bit file that when we record it, flac level

block size
Hi, we are implementing FLAC decode on an embedded device. FLAC, as you know, can have block sizes up to ~65K. For an embedded implementation, memory is limited: what would be the maximum block size we should support? We have seen the encoder encodes either 1152 or 4608 in its default setup. Should we support other block sizes? Also another unrelated question: given most existing files

Exact FLAC subset constraints
Finally, does this mean that: 1. Now any block size from interval [16, 4607] is subset, e.g. 588? 2. Now any block size from interval [16, 16384] is subset, (only) if sample rate > 48 kHz? And the third is the most interesting question: 3. Now not only constant (fixed) block size stream can be subset, variable block size stream can also be subset, (only) if minimum block size of this stream

BTRFS fails defragging

audio data encoding in FLAC: how complex ?
Hello ! The following algorithm describes Golomb(=Rice?) encoding: http://en.wikipedia.org/wiki/Golomb_coding#Simple_algorithm What is unclear to me is how many audio samples encoded with a fixed parameter (denoted 'M' in the wiki, which i presume is equivalent to the 'Rice parameter' invohed here): http://flac.sourceforge.net/documentation_format_overview.html But things are a

FLAC algorithms
Hi, Is there some documentation available about the algorithms FLAC uses? I'm talking about some high-level descriptions of the algorithms, which I can read without having to understand the source code. thanks in advance -------------- next part -------------- An HTML attachment was scrubbed...

educational doc about FLAC
Hello FLAC-dev, Do you know if there is some good educational documentation showing FLAC's internal design in a few steps, like this doc for monkeysaudio : http://www.monkeysaudio.com/theory.html If not, what is the principle of the algorithm in a few big steps (example : 1. Conversion to mid/side instead of L/R channels 2. Predictor 3. Entropy coding) ? Best regards. --------------

How is the MD5 hash calculated?
is it on a per subframe basis, and if so, is each frame padded if it’s not a multiple of 512 bits? or do I have to decode all the data, and run it over the decoded file at once?

Can I STOP decoding at an exact sample?
Hi guys, Thanks Matt for your prompt response about the C++ problem, its working great now! Again for my "virtual cdplayer", I am wondering if its possible to stop decoding within a large file, at the end of an exact sample? ie. I wish to play a song in the middle of a flac'd cd. Using the file decoder, I can seek to the start of the track(index 01 of the cds TOC), but I then want

Problem with CRAM and flac-1.1.2
A user of CRAM (http://swami.sourceforge.net/cram.php) sent in a bug report related to decoding of CRAM files. This issue occurs with flac-1.1.2 but not previous versions (such as flac-1.1.1). Note that the same file is used for this test (hopefully ruling out any issue with the encoder). Details of the issue: When calling FLAC__stream_decoder_process_single() the error callback is triggered

assign a cluster based on a variable
Hi, I have two matrices of the following form: cluster (n=18): 12062 1 12063 2 12064 2 12065 3 12066 5 KreisSA (n=2304) 12062 12062 12067 12065 12063 12067 I try to assign the cluster[,2] to KreisSAa by the follwoing loop: n <- nrow(cluster) KreisSAa <- numeric() for(i in 1:n){ KreisSAa[KreisSA == cluster[i,1]] <- cluster[i,2] } The result is a vector of the length n=4608

Yes, it would be nice if MetaFLAC will show minimum and maximum values of parameters (if are not constant/fixed) for the stream. And it would be VERY NICE if you implement
