That might be entirely due to SoX treating it as a 16-bit file, which it is
not; -100dB is almost

Possible bug in Opus 1.3 (opus-tools-0.2-opus-1.3)?
Hi!
Playing with Opus 1.3 I converted a tone sweep with a sample rate of 96kHz (just for fun). Before I had converted that from WAV to FLAC, and to Vorbis without problems.
With Opus I noticed that the file size for 48kHz and 48 kbps compared to 96kHz Vorbis at 31kbps is about double the size and it sounds even worse (than Vorbis) (there is a lot of noise in the lower frequencies when a low

Hi!
Excuse the delay, but I had to deal with a corrupted NTFS file system that ate many important files on an USB stick...
The FLAC version of the original is almost 6MB and it can be downloaded slowly from this time-limited link:

Q: "MP3 direct cut" for Vorbis?
Hi!
Maybe some of yopu know "MP3 direct cut" that allows you to cut out parts of an MP3 file as well as add some fading without having to re-encode the whole file. That's nice for making your own ring tones. Does something similar exist for Ogg/Vorbis?

Q: Tool to copy Vorbis comments to MP3 ID tags
Hi,
I'm wondering: If you have audio files like foo1.ogg and foo1.mp3, and the Vorbis
file has nice comments (title, tracknumber, artist, album, date, etc), is there a
tool to copy the information to an MP3 file on a "best effort" strategy?
I know that MP3 TAGs are quite limited regarding lengths.

Antw: Re: Q: Bandwidth vs. bitrate
Hi!
Useful advice, thanks! Actually I had been using foobar2000 to recode, because it just makes it so easy to convert multiple files while keeping the metadata (I confess, I'm a "tagger"). But it's easy to miss some encoder option when being presented some default suggestions in a dialog form...
Apart form that I always had the impression that Opus could be quite smart

Ogg Format
Hello Jean-Marc,
As an example, I am using the output of opus encoder to store the file as
the following format and read back the same during decode process, without
having much overhead. (Thought it would be useful to put a picture rather
than running text)

Ogg Format
The overhead of Ogg (in file size) is pretty small and it's efficient
enough for most applications (and uses far less CPU than the codec
anyway). If anything, you might want to look at optimizing the existing
Ogg implementation (e.g. like Tremor did in the context of Vorbis).
Of course, you're always free to design a new container, but I doubt
it's worth it and it's a lot of work

I'm not sure how you get a 7% overhead. In most uses I've seen, the
overhead is more around 1%.

Hi!
I was just trying libopus0-1.1-3.2.x86_64 and opus-tools-0.1.9-3.2.x86_64 on openSUSE Leap, and I was wondering:
opusenc does not display the file name it processes. In Lunux when you use some batch processing, it might be interesting! Example output for
"for f in *.wav;do opusenc --bitrate 160 $f ${f%.wav}.opus; done":

MP3/Vorbis/Opus: What I think I hear
Hi!
Sorry, I know the rules for comparing objective subjective listening impressions, but I'd like to know whether from the algorithmic or implementer's point of view the following personal impressions can be confirmed:
Comparing MP3 with Vorbis at rather high bitrates, I had the impression the Vorbis sounded more crispy, while MP3 sounded somewhat softened. I preferred Vorbis for that

You probably know already, but recently there's "fobbar2000 mobile" available for Android (I think Windows and iOS, too), and it plays Opus even ol older Android (like 4.0).

Using Samba and Rational ClearCase Tools
Hello,
We are using Samba to connect our ClearCase server to the Windows environment. Our original configuration was one server hosting all our VOBs and Views. We have Samba configured to allow mapping of shares to our ClearCase Windows Clients. Everything was working fine. Now we have set up a second server to host all our Views separate from the VOBs. So we have a View server and a separate VOB

vob file with lots of subtitles.
Hi there, first mail to this list, I hope to not disturb with my
question.
I'm trying to encode a VOB file (from a DVD) with ffmpeg2theora, but it
have a lot of subtitles (about 26) and I can't find the correct
--audiostream id to encode the file in my language. I have tried with
ids from 20 to 40 and so on and all times the audio kbps it's 0. mplayer
and VLC can play the .vob file
