Hello, for your consideration. The following patch moves the channel_pos() function from within the #if !defined(DISABLE_FLOAT_API). This change is required when compiling with FIXED_POINT and DISABLE_FLOAT_API defined. #### ### diff --git a/src/opus_multistream_encoder.c b/src/opus_multistream_encoder.c index 3efab53..6f3eb53 100644 --- a/src/opus_multistream_encoder.c +++ b/src/opus_multistream_encoder.c @@ -454,7 +454,9...

...rue 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 condition, so st->silk_mode.useDTX will be always disable Here is the code. #ifndef DISABLE_FLOAT_API st->silk_mode.useDTX = st->use_dtx && !(analysis_info.valid || is_silence); #else st->silk_mode.useDTX = st->use_dtx; #endif Is it a bug or are there any reason for this? In my opinion, the NOT expression should to be removed. I attached a fixed file. Pleas...

Hello, is the following a valid build option? ./configure CFLAGS="-g -O2 -DDISABLE_FLOAT_API" \ --enable-assertions --enable-fixed-point src/opus_multistream_encoder.c does not compile with that configuration. -- Pedro Becerra

...bspeexdsp has all the new components. Other changes include a new jitter buffer algorithm and resampler improvements/fixes. This is also the first release where libspeex can be built without any floating point support. To do this, the float compatibility API must be disabled (--disable-float-api or DISABLE_FLOAT_API) and the VBR feature must be disabled (--disable-vbr or DISABLE_VBR). You can download it from http://www.speex.org as usual. Have fun, Jean-Marc

Hi, I am working on trying to compile opus to be as small as possible. I have passed the FIXED_POINT and the DISABLE_FLOAT_API but I am looking into making this lib even smaller in size. Where can I find out about how to best strip this lib to only compile in what I need?

That's to say, the bit rate will be 96kbps, if the sampling frequency is 48kHz. The CPU usage is about 91% (911ms/1000ms), when decode 48KHz/mono/96bps. but encode requires more CPU (132%, 1312/1000ms). I will try lower bit rate...

Hi, First of all, I'm quite new to opus. I'm trying to use fixed point opus on an ATMEL AT32UC3B0512. I added the opus source into mine sw tree, I trim off code I don't use (eg. arm, x86 folders) It compiles, but the generated image is too big to fit in the flash. Have I any way to reduce the source footprint? (Eg. throw away unecessary files, if there are any..) Thanks, Daniele.

Greetings to All! Now I am trying to run speex on TI DSP... I need only coder+decoder+AEC. Bitrate 8000bps. Building with floating point support. What can i do, to reduce RAM consumption? I mean very serious RAM optimisations. Deleting not used structure fields, etc... May be I can do something with alloc... Help me to determine that it is possible to throw out. What is best result(in RAM
