Hello again. If you recall, I am the guy working on enabling Audacity to losslessly rearrange Ogg Vorbis files for my senior thesis. I have more or less completed the required modifications to Audacity to support this. You can read more about the work this entailed by reading my journal: http://www.reverberate.org/computers/thesis/journal Now my attention moves to the Ogg Vorbis code

Hello, I may be stupid, but I cannot find any data on how "expensive" the Vorbis Decoder is. Looking for an embedded solution I am interested in how many "MIPS" you need to decode a MONO audio stream at reasonable quality (44 kHz, approx. 100 kbps?) Can it be done in a microcontroller, or do I need ultra-expensive DSPs to do it? Thanks for hints Jens --- >8 ---- List

I've made a lot of progress on my lossless Vorbis editing project. I have a few more questions about granulepos issues I don't quite understand. granulepos is a property of Ogg pages, yet it is a field in the ogg_packet struct. When reading packets from an Ogg stream, the granulepos is set to -1 for all packets except the last packet in a page. From this I infer that - for encoding,

Hey guys, I just released my new MacOSX-based OpenAL implementation...part of it is a Ogg Vorbis decoder based on the 1.0 reference libraries. I spent some time optimizing them and found that many of the hotspots in libvorbis are perfect candidates for vectorization, so I wrote Altivec versions of them. The end result? Decoding of a .ogg file is between 30 and 50% faster on a Mac with an

hello, everybody! i record radio programmes through 'hard disk ogg 220'. as someone here has adviced me to do ;] it's brilliant. but after recording, i would like to cut off some material, to prepare an advertisement free version of the file. i use musicutter 071 to do this. but it gives me the following error when i'm trying to cut my file: 'Process time:

I see two solutions: 1) the new vcut which I reckon will fix the problem since it has to split and rebuild the audio in a new Ogg 2) an Hex editor, even if just to check what's wrong in the metadata section -Ivo

Andrew Williams <andrew.s.williams@adelaide.edu.au> has tipped me off that vorbis-tools uses a format specifier "%Ld" in vcut/vcut.c and ogginfo/ogginfo2.c. This is plain wrong. The L modifier only applies to floating point. The modifier corresponding to "long long" is ll, e.g. "%lld". -- Christian "naddy" Weisgerber

I've written an ogg-cutting program (sample accurate for cutting vorbis audio). vcut was the "inspiration" behind it, but vcut (as Michael Smith has said) is limited. Michael recommended i email this list to see if anyone is interested in this. I would just include the code but i'm not sure of the etiquette of that so... craig

I looked through the archives and I didn't really seem to find the answer to what my question. I used wget to get an audio stream from a site and now I would like to be able to split up the stream into the individual songs. The site is nice enough to encode the artist and track name in each new song. This info is displayed in Winamp when the song plays. Doing an xxd dump of the file I can

Dear vorbis-dev lurkers, I bring you the first beta release of vorbis-tools 1.3.0. It has quite a few new features and the final version will have even more, so I am sure it is to everyone's benefit that it gets as much tested as possible so we can do a quick release. Here's the changelog so far: * Fixed an error in configure.ac; --with-speex/flac work again (#1319) * Corrected

Hi there, in fact, my purpose is to write tool which will allow one to split ogg file with vorbis audio *and* theora video codecs, but at first I'd like to understand how the splitting of Ogg Vorbis stream works. So I looked at existing tools that split Ogg Vorbis audio files, i.e. `vcut' utility in vorbis-tools package, and Ogg plugin from `libmp3splt', but I found that engine code

Hello I have experienced some problems with vcut (media-sound/vorbis-tools-1.0-r1 package from Gentoo/Linux). I have a long live record I have encoded in OGG (maybe it would have been easier to cut the WAV file and encode the parts, but still). The file was encoded with oggenc from the same package as vcut. I have therefore tried to use vcut to split the long OGG file in several smaller files.

Hi, I've got alot of long 1-2hr files which I'd like to split up into 5-10 minute chunks. ?I think this should be possible using a small shell script and vcut, but my scripting abilities are lacking. ?Does anyone know of the existence of a script which would do this, or know how I'd go about making one? So say I had a 60 min file (60mins.ogg) I'd like to issue a command

Hello, I am student of IT from Croatia on finishing year for my bachelor's degree. For the graduate thesis I would like to contribute some open source project. For example it can be some bug fix. Language in I work is C. My knowledge is shown in programs on git profile: https://github.com/mkrajaci Project which I choose will be sent to my professor - mentor who will approve or not

This time in vcut: vorbis-tools/vcut/vcut.h:23 and 24. No, I'm not spending quality time with grep; I'm trying to compile vorbis with the native Sun Forte compilers.

Hi, Maybe this question is very trivial, but how do I cut a vorbis file into pieces? For example, I have a two hour recording in vorbis, and I want to cut it into 4 pieces, a half hour of sound each.

Hi, I am saving vorbis encoded stream in a ogg file. Which tool I can use to cut the file without any decoding / encoding? Just to delete unvanted begin and end. I am using UNIXes or Windows. Thank you, Jiri -- Jiri Navratil, http://www.navratil.cz, +420 777 224 245

Since it's been almost 2 years since vorbis-tools 1.2.0 was released, would it be reasonable to see 1.3.0 soon? There are plenty of changes in there that deserve to see the light of day - the ReplayGain support in ogg123 and the vcut fixes in particular have my attention.

I'm working with a streaming Ogg Vorbis system where I'm taking the stream output (from a darkice server) and saving it to hour-long files, then reassembling excerpts from these files (sometimes spanning two or three) into a single file for playback. I've got two problems (well, related to this, but anyway). 1) The "chunk" files I'm saving into have mangled headers. 2)

Hi, I have a question regarding vcut. In the man page, it says: DESCRIPTION vcut reads an Ogg Vorbis audio file and splits it at the given cutpoint, which is a sample number. <p>What I want to do, is to cut an Ogg Vorbis file at a given time. Say, I have an Ogg Vorbis file, which is 1 hour long, and I want to cut it into two half hour parts. With a fixed bitrate
