similar to: FYI: power consumption MP3 vs. Vorbis

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

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.

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? Regards, Ulrich

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. Regards, Ulrich

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

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": ---just on file--- Encoding using libopus 1.1 (audio)

Hello, with OpenSSH_2.3.0p1 running in HP-UX 11.00 I noticed that the "SD commands" (like "swcopy") produce the following error when being logged in via SSH: ERROR: RPC exception: "Who are you failed (dce / rpc)" 11/29/00 11:20:18 MET Ideas? Regards, Ulrich P.S. Not subscribed to the list

Hi! 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). Ulrich

Hi Ulrich, As Jean-mark recommended, we created "--enable-check-asm" config option to active OPUS_CHECK_ASM macros in the optimization, where the C function is called inside and the results of C and optimization functions are compared when encoding/decoding the real audio files.

Hi, this is a bit off-topic, but maybe you can help me: When extracting the autio track of a concert on video DVD, I noticed that the *.VOB files each contained only about 16 minutes of music, resulting in multiple files. I extracted to flac for further processing, but now I wonder how to make one continuous sound stream of those: Can I simple concatenate the flac files to make on big file

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: https://sbr5vjid0jgmce4q.myfritz.net:40262/nas/filelink.lua?id=0ba5a10529a6fe7b On the meaning of a logarithmic sweep: If you use foobar2000 and the
