AACplus
Sorry for the crosspost but it's relevant to Vorbis and Icecast I believe.
I'm seeing more and more streaming stations using AACplus, with many
listeners being amazed at the sound quality. Most say that a 48kb/s sounds
better than a 128kb/s MP3, which would put Ogg Vorbis at around 96kb/s IMO.
That means only half the bitrate is required in AACplus compared to Ogg
Vorbis for the same sound quality. Up until this codec was available, Ogg
Vorbis compared favourably with all the others.
Is there anything that can be done to bring Ogg Vorbis up to this type of
quality in the fut...

How can I optimize speex under SH
Hi,
I have just begin to look into Speex.Speex encodes and decodes fine under
SH platform (96MHz).
But encoding is taking lot of time i,e for 20ms frame it is taking ~890ms
to encode it. Which is very high
[To encode 96KB data it takes around 4.5min.]
Whether is this architecture suitable for speex ?
Whether writing some assembly instructions and some optimization will
bring down the encoding time to very low?
Which part of the code I need to write with the assembly or DSP
instructions?
Thanks,
Vinay

question about speex ccs
...that has been mentioned in the
readme-TIDSP.
the code runs perfectly ( i think) but it takes a lot of time for the *.out
file to "run".
the output file, which is supposed to be "maleout5x" has a size much bigger
than the input file "male.snd" (the input file is around 96kb).
is the program running correctly???
m desperate for the solution.
thanking you
nikhil

managed mode / max bitrate doesn't have effect
...2,
44100,
-1,
96000,
96000);
to initialize the encoding. To my surprise, it seems the maxbitrate
value of 96000 doesn't have an effect, the bitrate of the generated
vorbis audio hovers around 96kb/s, going up to 105 kb/s every once in a
while. If I call
vorbis_encode_init( &vorbisInfo,
2,
44100,
96000,
96000,

than the bitrate will vary between 83 and 98 kb/s approx. (The da...

opusenc equivalent of lame presets
> No comments?
Mostly no.
There are no presets because the encoder is smart enough to act
intelligently by default. The exposed knobs are exposed only for
those who know they actually need them. This is pretty much how Xiph
encoders have always been.
The programming API is a bit different, because there are more use
cases for streaming.

[Profiling][FFT][AArch64] FFT Profiling data on AArch64
Hi everyone,
I have profiled Opus on AArch64. I just run opus_demo with some pcm files.
Following is time proportion of FFT with different bitrate.
Bitrate | Time cost by FFT/iFFT
24kb/s | 15%
48kb/s | 15%
96kb/s | 13%
Any comment? I want some data close to real application, any suggestion?
Thanks,
Phil Wang

vorbis_encode_init() bitrate arguments - offtopic
...l
vorbis_encode_init()?
For rc2, it worked calling it the following way:
vorbis_encode_init( &vorbisInfo,
2, // two channels
44100, // 44.1kHz
-1,
96000, // 96kb/s
-1 );
And this produced an Ogg Vorbis stream of about 80 kbps on average.
But in rc3, the above call produces a circa 240 kbps Ogg Vorbis stream
(as reported by xmms). I tried putting 96000 in place of the -1 values,
and also putting 96 instread of 96000, but no luck.

Sample rates on ices
I'm trying to send out multiple streams. My encoder is a PII 233, so I
have to conserve CPU cycles. I encoded my mp3s as 96kb/s with a 44.1
sampling rate. I send my 96k stream without reencoding and it sounds
great. I also sned a 24k stream that is being reencoded from the 96k
mp3s. It works pretty good, the load on my linux box is about 0.5 on
average. However, the sampling rate is 8k. I'd rather bump that up to

need to up the knobs for listening on good output devices and digital

and on mid-end speakers I didn't notice quality issues.

sound quality / size
...und 30kb/s. During the encoding process i was
"warned" that the encoder is tuned toward 44.1kHz and encoding
files in any other may result in degraded quality. How worried
should I be? Is the advantage in size lost due to crappy
quality (versus 44.1kHz mono files)?
comment: twinhq 96kb/s and oggvorbis beta4 ~100kb/s are
virtually identical. however, once twinhq is dropped down to
80kb/s, all hell breaks loss and they sound shot-to-shit. they
hardly compare to 50kb/s OggVorbis files. I used the latest
version of the twinhq encoder (as of last week).

[Bug 799] scp incorrectly reports "stalled" on slow copies
...s "stalled". (Identified by code
inspection).
Secondly, the ssh process spawned by the scp process to perform
the actual encryption and transfer includes a substantial
internal buffer (>64KB) and appears to implement hysteresis.
ktrace output of a sample transfer shows a peak of over 96KB
buffered - at which point the ssh process stops reading until
the buffer drops to about 32KB. This implies that there is
approximately 64KB hysteresis and a transfer rate below about
13KB/sec can result in "stalled" reports.
This behaviour is a regression from from an earlier version of...
