I have just started trying Opus with a view to using it in a project. I am interested in embedded hardware and tried it on the Raspberry Pi using the raspbian distro. The version of libopus in the repos is 0.9.14. I installed this and tried encoding 2 minutes of speech from a librevox recording. It managed this at a respectable pace for complexity 10: Skipping chunk of type "LIST",

Christian, I will give 64kbit/s a try and post the figures. My own project is voice only and requires low bitrate so was hoping that it was just the way I was compiling and not an actual regression in speed for SILK. The raspberry PI is quite a cheap and handy reference platform though the ARM side is fairly underpowered but has a great GPU. It also has no audio in which is a pain for playing

Hello Everyone, I am using the opus 1.1 multistream APIs to encode a 5.1 surround stream on the server, stream it to client, decode it and capture the pcm data. I noticed that there was severe corruption/attenuation on one of the channels(specifically Back/Rear Right). This would appear to be the last channel in the stream. I am attaching an image of the PCM dumps from the original and the one

Hello Thomas and Amit, Thanks for your notice and the detailed decode performance report. I describe the details of my encode/decode test on STM32F407ZG. A. opus version: latest 1.2.1 (TI: opus 1.1.2) B. KEIL 5.23 (TI: ARM compiler tool chain 5.2.7) C. setup the encoder as the below (fs is the sampling frequency) enc = opus_encoder_create(fs, chans, OPUS_APPLICATION_AUDIO, &opus_err);

Hi. I found that DTX is always unavailable when DISABLE_FLAOT_API is not defined in OPUS_AUTO mode. As you know analysis_info.valid is alway true except NaN case and is_silence is alway true except digital zero signal case. In general, following condition will be alway true except exceptional case. (analysis_info.valid || is_silence) But in a code, there is a NOT expression in front of above

Hello, I am testing the command line based opus encoder/decoder tools and I have some questions regarding the information given by the encoder (see below as an example).

Hello!, i've just compared the 1.0.3 release with the master branch on a BeagleBone Black (AM335x 1GHz ARM Cortex-A8 with NEON floating-point accelerator) and Arch Linux ARM. At the moment I dont no why, but I see that 1.1 is much slower in encoding. Are there any default changes, that I missed and could explain this? Normaly I suggested a better performance with 1.1 and the ARM

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 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

Hey, I am having trouble with the size of the encoded bytes by Opus. I am also having issue with the Bandwidth ctl. Here is the scenario. If I encode 16khz sampled audio: opus_encoder_ctl(enc,OPUS_SET_MAX_BANDWIDTH(OPUS_BANDWIDTH_WIDEBAND)) opus_encoder_ctl(enc, OPUS_GET_BANDWIDTH(&x)) = 1102 opus_encoder_ctl(enc, OPUS_GET_MAX_BANDWIDTH(&x)) = 1103 average encoded size = 120 bytes if I

Resampling to 48khz speeds them both up but the disparity is about the same: 2.609 to 3.69.

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

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

Hi, I'm playing around using Opus in a 'chunked' streaming context, where chunks of media are served in separate HTTP responses. I am trying to hunt down the source of some clicks-and-pops during playback, and while it is very likely that these glitches are due to the low quality of my code, I wanted to ask if the admonition in the API docs[1] that "encoder state *must*
