Opus is specifically designed to survive tandeming but you need to keep the frames aligned and not mess with the gain, which your tools probably do not do.

Store the ELD correctly, not just enough copies of the first byte to pad out the given ELD size.

using iTunes i've noticed that AAC is very good at re-encoding own lossy sound. let's test Opus! neroaacenc.exe -q 0.75 -if 000.wav -of 001.m4a neroaacdec.exe -if 001.m4a -of aac001.wav wavdiff.exe 000.wav aac001.wav Comparing 000.wav - aac001.wav...

Commits 0a9e2b959 (drm/nvd0/disp: move HDA codec setup to core) and a4feaf4ea (drm/nva3/disp: move hda codec handling to core) moved code around but neglected to fill data up to 0x60 as before. This caused /proc/asound/cardN/eld#3.0 to show eld_valid as 0. With this patch, that file is again populated with the correct data. See https://bugs.freedesktop.org/show_bug.cgi?id=67051

Hello Jean-Marc: I've been watching the speex development from its inception because I and several Tech Startup Connection members have a very important application for this voice encoding/decoding. Further, we are quite familiar with ACELP as implemented in G.729. As far as I know Speex is also ACELP ... yes/no? Question ... what do you see as the advantages of ACELP compared to MP3? I

Standard AAC is on a par with Ogg Vorbis in my opinion, but it depends what type of encoder you are using as there are several. The only "free" encoder I know of doesn't use all the AAC techniques to provide the best sound quality and is worse than OV. The thread I started the other day was about AACPlus and not AAC. AACPlus provides much improved sound quality over standard

ICecast i capable of sorts of streams, that is not your problem. Your stream source client (DSP) is the part who must be capable of streaming the format you want. For AAC use oddcast DSP www.oddsock.org capabale of AAC, LAME Mp3, and OGG (Free to use) very good at OGG specially with the vorbis 1.1 aoTuVb3 DLLs For AAC Plus (HE_AAC) use Orban opticodec for PC (witch is capable of every bitrate

Well, in the world of audio compression it's never boring... :-) Full press release from Dolby: http://www.aac-audio.com/press/aac.pr.0104.AACencoder.html My comments: Looks like Dolby will start licensing AAC encoder that targets consumers and the products they use like CD rippers, jukebox players, etc. Also, it looks like that this encoder will be Low Complexity AAC ("The AAC Consumer

The open source AAC/HE-AAC encoders offer pretty poor audio quality. You really want encoder that uses the Coding Technologies, now Dolby, or Fraunhofer libs. That's what Orban Opticodec-PC uses. Sometimes you really do get what you pay for, and this is a perfect example. Greg. Orban Sent from Apple iTelePhone 5 StreamS HiFi Radio iPhone App High Performance HE-AAC First to bring HE-AAC to

Hello- You guys have done an excellent job with the Icecast2 server. I probably don't need to tell you that, but I did anyway. We are Coding Technologies licensees and have recently developed a streaming audio encoder supporting AAC/HE-AAC/aacPlus using RTSP/RTP, SHOUTcast HTTP/ICY, and Icecast2 HTTP/ICY, Orban Opticodec-PC. More information here:

Hi folks: this is my second question at this list and I wanted to mention that with answers and guides I got from 2 persons last time, I got a quite low rate stream in vorbis ogg, in about 5 minutes after reading what you wrote- Thanks! Well after that, I pointed my attention to the so called AAC, and after tweaking a bit I got my AAC stream up and connected to Icecast serv. I was a bit

Hi All, Got today the Orban Opticodec-PC encoder LE and it sounds great at 32Kbps and 44.1Khz and even lower it sounds great!! Now even people with dial-up can listen to FM quality streams! Got a test stream up, if you're intrested, with some rights free (RIAA free) music (dutch language made by a friend of mine). http://dir.xiph.org/index.php?sgenre=&stype=&search=doosfm there

looks like a job for liquidsoap! You can set up a playlist of any kind of audio. It will encode AAC and AAC+ both have small footprints with better audio delivery. I assume you are using mp3 as source because of limited space. The resampled sound will be no better then the mp3 source and in some cases will not be so good. regards Robert On 13/07/20 6:25 am, axeon wrote: > Hi all, I set

Hello all, I would like to know what kind of AAC can stream icecast 2.2.0. Is it MPEG-2 AAC or MPEG-4 AAC? How much efficiency can be gained by using this kind of AAC compared to MP3? -------------- next part -------------- An HTML attachment was scrubbed...
