Hello! Trying to compile, build, install and run Opus. My config: Ubuntu console (Windows 10 app). First problem, configure says openssl is missing. My system says that i have openssl already. Which openssl does it need? Using aptitude, i've installed everything with openssl name in it. That's tons of files and gigabytes of data. But it worked somehow. Second problem, flac-1.3.2 -

help compiling Opus! i'm stuck at opusfile. configure says i don't have openssl package installed but Debian 9.4 thinks i do. this Debian only have Opus 1.2-alpha2 package, so i need to compile Opus by myself. seems even Debian developers having trouble compiling latest versions of Opus, what chances do i have to succeed? -------------- next part -------------- An HTML attachment was

tracked down the spectogram atrefact source; it comes from the resampler. so it's not really a bug, just a nuisance. let's hope in the future Opus will be able to save bitrate on simple audio parts as all other lossy and lossless codecs do. i think opus decreasing bitrate only when it thinks that audio is too complex for human to hear difference. that's a bad attitude.

Hi guys, as MP3 and Opus have very similar objectives, I think the original poster's question was a valid one: Why does Opus have more artefacts in the lower frequency ranges than MP3 has? The spontaneous suspect that lower frequency artefacts may be more noticeably than higher frequency artefacts seems plausible, also. Is it a matter of energy (which is higher for higher frequencies)? When

Good morning. I've ran a test against MP3 format. Code: (first convert tested audio file to 16 bit 48khz with sox.exe if needed) lame.exe -b 320 48khzfilein.wav -o fileout.mp3 lame --decode fileout.mp3 -o fileout.mp3.wav opusenc.exe --bitrate 320 48khzfilein.wav fileout.opus opusdec.exe fileout.opus fileout.opus.wav wavdiff.exe 48khzfilein.wav fileout.mp3.wav -diff fileout.mp3.delta.wav

I brought this up 12 months ago or more. I believe the low-pass filter defaults too high with quality -1 in Vorbis 1.0. Is this going to change in the future? I think it should at least cut off at 15khz not 16khz and perhaps even 14khz. I believe it's important when streaming. Removing some of the higher frequencies compared to removing more of the audible sound makes more sense to me.

I've upgraded mine Ubuntu distribution and mouse wheel does not work anymore (just in Wine), any suggestions?

Hi, I need to plot spectrogram of a waveform.What package offers this? -- Rajesh.J [[alternative HTML version deleted]]

I know that there is a function, (spectro3D), that produces the Power Spectrogram. Are there R functions that produce the Frequency Spectrogram and the Phase Spectrogram? Thank you for your time. [[alternative HTML version deleted]]

Greetings Samba team, It has been a long time since I needed to ask a Samba technical question. Server and workstation are both running the latest Samba packages via Ubuntu 16.04 LTS.

The last time I wanted to record a voice announcement on my computer was a few years back, and as I recall I hooked up my Microsoft Lifechat headset and used Audacity to do the recording. Now I want to record a "recitation", which consists of me playing my piano and talking over it. I have a Casio CDP-230 digital piano but I've never tried hooking it up to my computer and making a

Hello. i have over 30GB of Opus music and noticed that solo instrumentals and solo vocals uses more bitrate than full-mixes. Here's example where Opus 1.3 used 190 kbps for piano solo and 159 kbps for full-mix. (--bitrate 160 --music) Download example piano solo 15MB: https://mega.nz/#!wLBz3AZT!YmqQMkAGqc4kGHumNWZAfB7Cmcf4vFlHpT6IiiAVCNA FLAC uses 2 times less bitrate for solo than full-mix

I can get the interactions between factors like this: > idx=c(1,3,6,9) > jdx=idx > levels(interaction(idx,jdx,lex.order=TRUE)) [1] "1.1" "1.3" "1.6" "1.9" "3.1" "3.3" "3.6" "3.9" "6.1" "6.3" "6.6" "6.9" [13] "9.1" "9.3" "9.6"

While significantly larger, Opus had produced significant ghost noise (much less than Vorbis did)... I experience the "same" low level noise even in a wav file, even on

Thanks Andy, helpful as always! 1 is a possibility, but not ideal for us. Could you elaborate a little on 3? I don't really know what a jump stub is, but am guessing it's a kind of "alternative symbol" which would just act as a middle man to invoke the "real" symbol in the static library. If that's the case, I can think of a way to implement it for specific
