I have got ices running with quality -1 (and on my roommates crappy computer speakers it sounds damn near the real thing - better than FM radio anyway)... I'm just wondering if it's posible to configure it with a maximum bitrate, or a nominal bitrate. i.e. to use managed bitrates instead of quality (I know it's a no no, but this is streaming!).

Hello, good morning ! Running Icecast2 and Ices2 with live audio from Line IN, what is the correct way to change the bitrate ?. In the Icecast2 configuration file I set: <mount type="normal"> ????<mount-name>/entzun.opus</mount-name> ????<bitrate>128</bitrate> </mount> But it seems that is not enough since the bitrate does not change. Receiving the stream with Rhythmbox,?a...

Hello developers, I have a question about supported bitrates for SPEEX. Regardless of whether I specify a 10kbps or a 8kbps bitrate, the encoded .spx file is the same size and have the same PESQ value. This makes me wonder if SPEEX supports arbitrary bitrates, or only a certain set. A few more details about my configuration: I am using SPEEX encoder ver...

...hments/20041014/25f999a2/attachment.htm -------------- next part -------------- ? dear All, Iam working on OGG VORBIS TREMOR code to port and optimize on ARM processor. Can any one make me clear regarding the relation ship between this 1. What is the relation ship between Quality factor and Bitrates? As vorbis is a VBR algorithm, many bitrates will be selected encode and decode a stream? If so how quality factor is related to bitstream? 2. In many web pages(I dont have the links to pages) related to Ogg Vorbis information I read higher the bitrate we select, t...

Hi guys, I'm using Opus for speech in wide-band mode (sampling rate 16000) and 20ms frames with signal type set to SIGNAL_VOICE. I have a few questions here: 1. When I choose VBR mode, the codec seems to choose the bitrate on its own. However, that seems to be an issue on mobile devices. In some cases, when I configure the bitrate to say 20kbps, I see that the outgoing codec bitrate at runtime is sometimes far less (11-12kbps even). That leads to a lower received audio quality. When I choose CBR mode however, the ou...

Hi, I'm using the latest version of libspeex (checked out today) and have some problems with checking the target bitrate in the encoder. Calling: peex_encoder_ctl(globals->enc_state,SPEEX_GET_BITRATE, &bitrate); Seems to set bitrate to 24600 no matter what the qualitysetting is.. The functions used previous to this call is: peex_bits_init(&globals->bits); globals->enc_state = speex_encoder_init(&...

Hi All, As specified in earlier email we have released the trial version of the ogg vorbis decoder. Along with the decoder we have released an experimental version of the bitrate peeler that we have used to test the decoder for bitrate peeled inputs. We have made the executable of the bitrate peeler available from our website downloads section. www.vinjey.com/ogg_downloads.html We need inputs with respect to results of this bitrate peeler. This bitrate peeler r...

Hi, I'm trying to cover all Speex configuration options to set quality/mode/bitrate in my application and I was wondering if the following all makes sense: - abr_bitrate - use average bitrate and set it using bitrate parameter - SPEEX_SET_ABR - cbr_bitrate - use constant bitrate and set it using bitrate parameter - SPEEX_SET_BITRATE - cbr_mode - use constant b...

I'm sorry if this question has been asked before; I've looked through the archives and haven't seen anything. The problem I'm seeing is that oggenc's VBR encoding doesn't seem to pay attention to any sort of bitrate limitation, either the -m or bitrate_hard_min settings. It isn't that it temporarily dips below the minimum; the average for the whole (in this case, easily compressible) file is 10-20% too low. I see roughly the same results on an old 1.0.1 version of oggenc as well as a new vorbis 1.1-link...

I had expected that the default bitrate for the encoder would be the same as setting it to OPUS_AUTO, but I'm getting difference results: >opusenc --comp 4 sample.wav sample.opus Encoding using libopus 1.3-rc2 (audio) ----------------------------------------------------- Input: 8 kHz, 1 channel Output: 1 channel (1 uncouple...
