similar to: test vectors for OggVorbis encoder

We are working on OggVorbis encoder. In the porting effort we are trying to convert it to fixed point code (both 32 and 24 bit fixed point). Now the issue is how we do the testing. What should be the criteria for our testing. Does anybody has any idea how compliance testing (i.e. some objective tests) is done at encoder side? What is the criteria of testing at the encoder side? If anybody

Hi, Have anybody worked on converting OggVorbis encoder floating point code to fixed point (32 bit or 24 bit). How do you handle _vp_noisemask in that case where precision goes upto 40 bits. Any help available? Parul Embedded Engineer Einfochips Ltd

Hi, Does anybody know how codebooks are generated in OggVorbis encoder? We are porting oggorbis encoder on embedded platform for which VQ codebook memory is hugeeee to imagine. How can we reduce that? Can we do VQ with less codebooks and if yes how? If any help available? Parul Embedded Engineer Einfochips Ltd

We are implementing oggvorbis decoder on embedded system. In that we want to have support of chaining and grouping. If somebody can throw some light on how it can be implemented, it would be gr8 help. Regards, Parul -------------- next part -------------- An HTML attachment was scrubbed...

For testing the encoder i needed test vectors. thanks for the links send by members. Those links are useful, but contain test vectors corresponding to 44 KHz only. Does anybody has any idea where i can find test vectors of other sampling rates i.e. 48 KHz, 32 KHz, 16 KHz, 11 Khz, 8 KHz. ? Thanks, Parul Embedded engineer Einfochips

Hi. I'm wondering if anyone out there can give me a little help trying to figure something out: I presently am running CentOS4.1 with GNOME as my desktop (It runs quite well, I must say!). I just have a little curiosity: I have a few audio files (.wav, .mp3 and .ogg) and I like to "preview" them. When run my mouse over the .wav files (and mp3 files) the

Dear Sir, I am a DSP Engineer working in the field of Audio Standards and general Signal Processing Algorithms. I am very much interested in knowing the algorithms which make OggVorbis a reality. Kindly send me the link which will lead me to the algorithm description or pseudo-code. Thanking You, Sincerely, Tom Xavier. <p>--- >8 ---- List archives:

In case people on the list don't know it, A Vorbis tester (who's email I've lost! If you're on the list, speak up!) is maintaining a vorbis audio quality test page: http://hem.passagen.se/ingets1/vorbis.htm He's doing us the great service of hunting down samples that break Vorbis (so we don't have to :-) In any case, it turns out that the trumpets in the dr4 sample

Could any one suggest me in how to get the duration of an OggVorbis File.I am really caught up in this, as it seems to be complicates as the OggVorbis is a variable bit rate.

I read something about the copyright expiration on the MP3 format that could affected it’s use in Ices. MPEG-1 Layer III (popularly known as ‘MP3’) has been patent clear since 16 April 2017. One other live encoder option that supports both OggVorbis and OggVorbis as well as MP3 is

Hi All, Are multi-channel (more than 2) formats fully supported in the OggVorbis specification ? I couldn't find any information about multi-channel support on xiph.org. I've used 'oggdropXPd' to encode a 5.1 wavefile and the Xiph OggVorbis libraries (vorbisfile.dll) to decode the file successfully, however the order of the channel interleaving is different to the original wave

Hi All, I am planning to implement Ogg Vorbis Decoder on a 24 bit DSP. I have following doubts: 1) What is min and max bitrate? 2)What is max Audio Packet size ? 3)What is the max size of setup header? 4)Any idea how to start for making a 24Bit fixed point reference code? Shall I start with floating point or Tremor or Tremor Low Mem Version? 5) What window sizes in Ogg Vorbis are normally

Hi list, It seems that when playing several OggVorbis files under xmms, there is a memory leak. It's a rather annoying problem because when you have a playlist of 100+ files, xmms will at the end eat something like 100M or more.. Such a memory leak have been reported inside xmms-1.2.2 code and I could see it playing Ogg files and mp3 files ; upgrading to 1.2.3 solves the problem with mp3

Hi, Thanks for provoding the snapshot. Now it refers to following folders which are not included in the package! ../../pthreads ../../oggvorbis-win32sdk-1.0.1/include 1) Can I use http://svn.xiph.org/trunk/ogg insted of oggvorbis-win32sdk-1.0.1? 2) Where do I get pthreads? 3) Is svn for libshout available for public read access?

Using metaflac (1.0.3) like this: metaflac file.flac --set-vc-field=title=test??????e? The vorbiscomment will not be UTF8-encoded, instead they will be stored directly as ANSI. When trying to add some more comment, it gave the following error: ERROR: writing FLAC file file.flac, error = FLAC__METADATA_CHAIN_STATUS_OK Does that mean that weren't enough room for the comments? But

I am writing a long-run sound recording application using OggVorbis. The user can adjust sound quality parameter to make balance between storage space and sound quality. The input sound is 22050Hz, mono. To maximize the recording capability on a given storage volume, we want the result bitrate as low as possible. I use -q0 parameter and it produces a 32.0kbps stream. It is too high (our

Ok, so I've taken hold of this, and since this appears to be the only thing holding up 1.0.1, I have done what I think closes the loop...Based on the conversations here on the list I have made the following changes to the vc6 project files : - consistent runtime linking. They are ALL now using the Multithreaded static runtime. Hopefully this makes the generated DLLs the most portable. -

I released "aoTuV" beta6 of OggVorbis encoder, library. ---------------------------------------- CHANGES (for general) from beta5.7 # Libvorbis aoTuV was unified with Xiph.Org's libvorbis1.3.2. # Pre(post)-echo of the specific pattern was improved. # The bit allotment when sound of the different type coexisted was improved. # The calculation method of dynamic thresholds
