similar to: [fwd] help encoding low-quality audio please

Hi everyone. I did a rough recording of an instrumental (electric piano sound) & e-mailed it to a friend in Vorbis 11025 Hz / mono. I was seeking a bitrate in the range 8-16k/sec. The song is 2:55 in length. q=-1 happily achieved a 12.6k/sec bitrate. All file sizes I mention in this are for files without informational tags. And I hope this isn't interpreted as trying to plug my music or

Hello. Attached are some patches that some Debian users of vorbis-tools have sent to our BTS over the years (numbers refer to Debian bugs). It'd be nice to see them integrated. They apply cleanly to SVN as of today. The largefile_support one is a bit bigger than just the configure.ac since the submitter adviced that config.h got included in all C source files before the standard includes,

Hi all! I ran across another song that oggenc seems to have trouble to encode. The intro of U2:s "Grace" gets its right channel messed up by oggenc, even at the highest bitrate. Why is the bitrate only 218? Isn't that awfully little when asking for 320? Qualityflaws like these is the reason i prefer mp3 and mpplus today. But vorbis is getting better for every beta, so keep up the

Hi I made a CD-backup with cdparanoia | oggenc and I tried to use different values of -q listening to the effect by cdparanoia | oggenc -o - | mplayer -. The best quality was 8 -- why?

This is probably addressed to Michael Smith :) I have been playing with the latest oggenc and full libs from the SVN attempting to get the hard min/max limits to work with the quality settings. The way it is currently set in encode.c does not appear to work; ie., the result is the same with or without the hard limits set. However, if I amend the code such that management is NOT turned off if

Hello... I was very surprised when I found, that oggfiles created with RC3 are much worse than files made with RC2. I have some example sound file set up for you on the net. The difference is *obvious*. While RC2 made ogg-files, which I would say are perfect (at least I cannot hear a difference to the original), the quality of RC3 is *bad*. Let me first say, that I used libvorbis0, libogg0

Hi, I hope this is the right address for this e-mail... I've been experimenting with OggEnc v0.5 (beta3), and I've experienced a wierd artifact with a certain song ("Theme From Mission Impossible" by Larry Mullen and Adam Clayton). It's pretty subtle, but it's audible. I've ripped the wave from the original CD, and encoded it at average bitrate

I use "jack" for my ripping, changed a few things here and there to get the "right" switches for oggenc. I reported a wishlist item to it's author to make the defailt -q instead of specifying bitrate. So for the time being he has set it to -q5, without the ability to specify quality on the command line, like bitrates for mp3. -q5 sounds high to me. He said it should be at

I'm a bit confused about VBR with Opus. I see that the default is VBR, but I don't see any way to specify a quality setting. I can set a target bitrate, but that's definitely not what I want; I want a constant quality level, like "-q" in oggenc, and for the encoder to select bitrates based on the desired quality. For example, for playback through earbuds or laptop

Greatly concerned for size, i just ripped an audio cd @ 22050kHz and mono sound. Encoding using 'oggenc -b 1 -', the resulting Ogg file is around 30kb/s. During the encoding process i was "warned" that the encoder is tuned toward 44.1kHz and encoding files in any other may result in degraded quality. How worried should I be? Is the advantage in size lost due to crappy

Hallo altogether! First of all I want to thank the developers for the great codec! But I have the following problem now: I have built my own Linux from Scratch and also compiled everything that is necessary to have ogg and vorbis and tools for de- and encoding. Just the encoding turned out to have very poor quality independent how high I set the quality level. It has some kind

Hey folks. I know tags aren't anyone's favorite subject, but I'd like to make a suggestion for a tag that I think is quite important -- a quality tag. So important, I think, that oggenc really ought to automatically create one when the -q option is used. As all of us know, in the Vorbis codec the quality of the stream is often a more important (and more informative) value than the

First let me say that I was absolutely astounded at the sound quality when using oggenc at q = -1 (around 50 kbps). So much so, that I'm anxious to try some of the lower bit rates that were mentioned in the announcement for 1.0: ... audio and music at fixed and variable bitrates from 16 to 128 kbps/channel. But I am having trouble finding how to use either oggdrop or oggenc to get these

Hello, While tweaking the stream configuration interface in the Airtime broadcast automation tool (http://www.sourcefabric.org/en/airtime/) we noticed that Liquidsoap uses the zero to one scale for Vorbis quality, rather than the more familiar zero to ten scale used by oggenc. It seems I'm not the only person confused by this: http://ffmpeg.org/pipermail/ffmpeg-devel/2009-January/067964.html

First of all, keep the replies on the mailing list. Are you subscribed to the mailing list? On Aug 24 09:44:56, nguyenquocthao00 at gmail.com wrote: > The file ogg is the same, I know that.
