...ckSize field can be odd to represent the size of the valid data. > > However, the chunk itself must always be an even size. This requires a padding byte at the end of a chunk before the next chunk can begin, or before the end of file. The latter case is the one that most often occurs in buggy RIFF writing programs - the last chunk will have an odd ckSize and the file will be one byte shorter than a valid RIFF. The problem was in the size of RIFF chunk. Should RIFF chunk size include the padding byte of a last chunk? For example, a program writes a RIFF WAV file which contains 16-byte ...

This patch should fix ticket https://sourceforge.net/p/flac/bugs/419/ and its duplicate https://sourceforge.net/p/flac/support-requests/152/ some programs write odd value to ckSize of RIFF chunk.

The ckSize field can be odd to represent the size of the valid data. However, the chunk itself must always be an even size. This requires a padding byte at the end of a chunk before the next chunk can begin, or before the end of file. The latter case is the one that most often occurs in buggy RIFF writing programs - the last chunk will have an odd ckSize and the file will be one byte shorter than a valid RIFF. Some RIFF readers blindly expect an even number of bytes in every chunk, and seek past each chunk to see if another chunk exists afterwards. In the case where the last chunk ends a by...

...r the MP3 to get at the ID3 info in the file. Which libs does swfdec require to pull the MP3 stuff properly - I may be missing some vital library in my gentoo build that I can go and build and recompile the tool to get MP3 extraction to work, I'm hoping. :) localhost 13 # file *.mp3 110.mp3: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, stereo 44100 Hz 111.mp3: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, stereo 44100 Hz 56.mp3: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, stereo 44100 Hz 84.mp3: RIFF (little-endian) data, WAVE audio, Micr...

Hi, how can I convert .wav files to .WAV: # file greet.* greet.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, mono 8000 Hz greet.WAV: RIFF (little-endian) data, WAVE audio, GSM 6.10, mono 8000 Hz using 'sox'? Thanks -- Domenico Viggiani

...CM codec there will be a lot of Windows GUIs for FLAC. I'm writing this message to talk about the FLAC format. The GUIs for the Audio Codec Manager, including Winamp and Windows Media Player for decoding and CodAxe for encoding, can use any format with a codec registered in the system using the RIFF file format. In this ACM codec's implementation, all data, including the "fLaC" marker and the metadata blocks, is placed by the Audio Codec Manager encoder's GUI in the RIFF's data area. Actually, I couldn't find any other way for doing this. The inconvenient is that the...

So i'm trying to write an app that enocodes WAV files to "Ogg in a RIFF-WAV" files. Theese are used in Fruity Loops, and since the software itself does not have this feature i wanted to write one myself. The point for it is to save space when sharing "zipped loop packages". Such packages contain the samples (WAV) and the song file (FLP). At first i wrote...

just recently I have finished implementing support for saving non-audio chunks in RIFF WAVE and AIFF with the FLAC file in application metadata blocks, and restoring them when decoding. you can read about more about it here: http://www.hydrogenaudio.org/forums/index.php?showtopic=56968 the zip file there has windows binaries; CVS HEAD has everything checked in if you need a differe...

So, I saw a form of wav header I didn;t know about today. It's not in my (admittedly aging) copy of the RIFF spec from M$, but it's pretty clear how to handle it (mostly in the context of OggEnc). Here's a dump with od -c: 0000000 R I F F 370 357 l 002 W A V E f m t 0000020 020 \0 \0 \0 001 \0 002 \0 D 254 \0 \0 020 261 002 \0 0000040 004 \0 020 \0 P...

Not sure if this belongs here or in flac-dev. I am subscribed to both, so flop it over if fits better over there. Looking at the Changelog for FLAC 1.2.1 (17-Sep-2007), it says: "With the new --keep-foreign-metadata in flac, non-audio RIFF and AIFF chunks can be stored in FLAC files and recreated when decoding." Where can I find more detail on what is a "non-audio" RIFF chunk? Ambisonic ".amb" files are WAVE-EX files with a non-standard GUID in the 'fmt ' chunk. I want to work out is this c...

Hi All, Why is it that sometimes when I encode a .wav file then decode it again the length of the generated file is 2 bytes shorter than the length of the source file? The discrepancy in length occurs in the header and the remainder of the data from there on is identical. It seems to me that what appear to be length fields in the header is adjusted appropriately. I suspect that this is not a

...ose below and Asterisk will freeze completely, and the only way to come out of it is with a kill -9 . Is mpg123 causing my problem? Is there a specific format of MP3 that should be used/avoided to not have errors like these? Any help would be greatly appreciated. Thanks, MATT--- ERRORS: Skipped RIFF header!

...sampling rate of 4660 and was able to reproduce your problem. flac works fine on the other files, which have more normal sampling rates (8000, 16000, 32000, 44100). If I use sox to convert the sampling rate of the problematic file, flac works on the result. In my case, the files I tested were: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, stereo 44100 Hz (works) RIFF (little-endian) data, WAVE audio, Microsoft PCM, 8 bit, mono 4660 Hz (fails) RIFF (little-endian) data, WAVE audio, Microsoft PCM, 8 bit, mono 8000 Hz (works) The third is just a sox-converted version of the seco...

...out, or there are pieces which are vague. In some cases, the various resulting symptoms may appear the same to the end user, but they actually have quite different causes when examined in detail. There are a couple of issues which fall under the generic category of "odd" sizes in RIFF/WAVE files. The first is one that I tried to describe in detail, but turns out not to be an issue with the file in question, although it is a common error. The second issue could probably be described more clearly. 1) At the most basic level of the specification, all RIFF/WAVE chunks mus...

Hey Everyone, First time poster! woot! Can someone please point me to a Wiki, FAQ, web page, that I can reference to help me debug why my installation of the TextMate Bundle doesn''t work? Am I supposed to install the gem, then install the plugins into a project, then install the bundle before the bundle can work? I can run ''rake spec'' at the command line just fine;
