Problem compiling opus-tools-0.1.7
Hi, Seems like it's not linking with libm. I suspect it has to do with linking statically with libopus.a (is that intended?). Maybe opus-tools relies on the fact that libopus is linked with libm and doesn't explicitly add it? Greg?

Problem compiling opus-tools-0.1.7
Hi I'm having a problem compiling opus-tools-0.1.7. Version opus-tools-0.1.6 seems to compile OK. I've tried with opus-1.0.3 and opus-1.1-beta. The errors are like this:- "undefined reference to `sqrtf'" etc. This OS is Peppermint Three, similar to Ubuntu 12.04. It uses:- gcc --version gcc (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3 Google says it's maybe something to do

opus-tools resampler
Hi, I've noticed that the opus-tools is using a really old version of Speex's resampler code - a version that I've seen fail in the wild first-hand under low resource circumstances. I've actually submitted patches for some issues in the Speex resampler a while ago (and IIRC they were accepted): http://lists.xiph.org/pipermail/speex-dev/2009-November/007541.html ,

1.1 Much slower on Raspberry Pi
Resampling to 48khz speeds them both up but the disparity is about the same: 2.609 to 3.69.

1.1 Much slower on Raspberry Pi
Hi Stuart, you are compressing it at 6kbit/s. Then, then SILK mode is probability used and the Silk mode is much faster than CELT. Do you also some figures at 64kbit/s? It is strange that Opus 1.1 got slower in the Silk mode - may the speech/voice selection adds some overhead. I would be interested in seeing the performance of the 64 kbit/s in both Opus 1.0 and Opus 1.1. With best

Opus on MIPS performance
Hi All, First time poster to this group, please ignore my ignorance? I?m trying to use Opus 1.1 on a 400MHz MIPS 24k CPU (AR9331, specifically, like in the Arduino Yun). I?ve successfully built (I think) opus-1.1 and opus-tools-1.8 and they run, but are dog slow. opus-1.1 does have the ?enable-fixed-point option set, as this chip only has soft-float. My short test file (less than one

Opus Major Version Benchmarks on Raspberry Pi
I wanted to roughly benchmark how the different version of libopus performed at each complexity level for a 6kbit/s output opus file. This was conducted on a Raspberry Pi so it is a constant hardware platform. This was done on an early Pi so only 256MB RAM but it was never used up so should not make a difference. I compiled the three final versions of each major release of libopus so that was

Help building OPUS library using FIXED_POINT option
Hi, We are rebasing our audio compression subsystem using OPUS rather than SPEEX. The platform is Android but this piece is written in C code: we need to support armv5/armv7/x86 architectures.... and we use the released opus-1.1beta package from here<http://downloads.xiph.org/releases/opus/opus-1.1-beta.tar.gz>. A lot of our OPUS build system + code to drive the audio compression has been

Opus Tools -- low bitrates, new features in 1.5, "expect-loss"
> To be clear: did you mean the opus output of opusenc > or the wav output of opusdec? I meant during the decoding. There's one significant difference between how Opusdec deals with resampling and how, let's say, MP3 decoders usually deal with resampling. If I make an MP3 at a very low bitrate and if the encoder decides (because it's too low) to internally resample my audio

Compiling FFmpeg with libopencore-amrnb and opus-git.
It appears that both Opus and amrnb have a function called preemphasis(). In the short term, your options are: 1) Not building statically 2) Renaming that function in the Opus code 3) Renaming that function in the amrnb code I can do the rename for the next version of libopus.

Opus cmake build
Hi Mark, Thanks for the feedback. By default CMake is building the static library in debug, to get other things one has to explicit turn it on. To build in release mode for CMake you use the following flag: -DCMAKE_BUILD_TYPE=Release https://cmake.org/cmake/help/latest/variable/CMAKE_BUILD_TYPE.html CMAKE_BUILD_TYPE — CMake 3.14.1
