similar to: Silence causing encoder slowdown on 32 bit architecture

Hi all, I noticed some odd behavior with the Opus encoder, and I was wondering if this is a known issue. First, note that this problem occurs when the Opus encoder is created with OPUS_APPLICATION_VOIP, there is no issue if the encoder is created with OPUS_APPLICATION_AUDIO. If compiled for a 32 bit architecture (i386), the encoder experiences significant slowdowns when regular audio is followed

Thanks for the reply. For my application I unfortunately need a better signal reconstruction. It's not necessarily a problem that the constant DC voltage is removed, but the audio signal will need to be more exact because it's also studied visually. To be more exact, I need to record and transmit audio data recorded from animals (mostly birds). Are there ways to achieve a more similar

I'm new using OPUS and I've implemented the OPUS lib under PIC32MZ, using the MIPS configuration. It compiles correctly and it seems that all the procedures invoked returns no error. However, when I excite the encoder with a pure 1 kHz tone, the encoding/decoding procedure returns al the samples to silence (the buffer is filled with 0x8001 or 0x7fff). The configuration is 48000 sps, 64kHz

Hi all, i am trying convert pcm (16bit pcm) stereo file to mono pcm file using opus_encode and opus_decode, i am able do this but i have doubt about TOC byte after opus encode. below is how encoder and decoder structures are used to do encode and decode file opus_encoder_create(8000, 2, OPUS_APPLICATION_AUDIO, &err); opus_decoder_create(8000, 1, &err); after opus encode bits looks like

Hello, I have an p2p voice chat application using WAVE PCM (winmm). Now i am trying to add opus encoding to it to send it over the TCP/IP and then decoding it back to play - but without success (without opus it works ok) Here is an example of my code. I get message from input device then encode with opus then decode it back to output wave header and play. Doing it i hear only noise in my

First of all Hi everybody and thanks for this cool software called "wine" Well I've been looking for Help... I Know there is a lot about it... but I just wanted to know.... I have an AMD sempron 2500+ Gforce 6200 (256 MB), 1GB ram, with Ubuntu 8.10, Kde 4.1 (desktop effects disabled, no slowdowns in opengl aplications). Everything is ok, no sound problem.. no grafic problem. For

Hi there, We're currently attempting to explain a slowdown of an LVQ-type parallel analysis we're working on. We are benchmarking our analysis running over openMosix against the same running via SNOW for R. Both perform similarly on small datasets, but on large datasets SNOW drastically outperforms openMosix. However, these results are achieve running SNOW on the default RedHat

Hello again. Our production cluster has begun experiencing some vicious slowdowns that may (or may not) be related to the filesystems. When the problem occurs, the load average on the servers jumps up to 30 or higher. Usually one node will climb while the other drops, then they will switch places a few minutes later. At one point, we had one node's load average up over 300. Our site

The Windows98 explorer (and possibly other programs) incorrectly set the "sync" bit in write requests to network shares. This causes an enormous slowdown as Samba (quite correctly) does a fsync() on the file after each write.

If you encode with int iByteSizeEncoded = opus_encode(m_enc, m_ShortsInput, (1920/sizeof(short)), m_EncodedBytes, (960*6)); ... the byte size is 120. I thought that an odd value like 359 has to be a fault on my side. I thought it would be a multiple of something. So 359 is really correct??? Thank you for clearing this up.

I have a CentOS 6 system that has suddenly starting significantly slowing down. It runs a django app with an Apache server and MySQL server. There is plenty of disk space and no process seems to be hogging the memory or CPU. But operations that used to take 5 minutes are now taking hours and hours. Coinciding with this slow down I see these messages in /var/log/messages (this is hand typed, as I

Why does opus_encode return 359, and not 360, please? This is my code: int iShortsRead = fread(m_RawBytes, sizeof(short), (5760/sizeof(short)), fin); for(int i=0;i<iShortsRead;i++) { opus_int32 s; s=m_RawBytes[2*i+1]<<8|m_RawBytes[2*i]; s=((s&0xFFFF)^0x8000)-0x8000; m_ShortsInput[i]=s; }

I am experiencing slowdown due to changes introduced after 3.0.1 to the various DC lookup routines. I have it narrowed down but don't know where to go from here.
