search for: speex_set_complexity

Hi there According to the manual SPEEX_SET_COMPLEXITY sets the allowed CPU usage for the encoder. I've tried changing the complexity from 1 to 10 to see if I were able to notice any difference in sound quality but I have not. Shouldn't the effect of a high complexity increase the sound quality? Kind regards Bjoern _______________________...

...I was wonder how Speex handles (if at all ) lost packets when decoding the bit-stream . 1. Does Speex has any mechanism to handle lost packets (like AMR has for example)? 2. I am using Speex in a constant frame size (160 bytes), narrowband, VBR off, SPEEX_SET_QUALITY = 3 and SPEEX_SET_COMPLEXITY =1 . I encode speech stream and sending the encoded packets to the their destination. If I am loosing 4 continuous frames during the transmission , what can I expect to hear? noise ? quiet ? echo ? Can anyone help me with this issues ? Regards, Uri Rattner -------------- next part -...

Why? In my previous installation of libspeex I had the same problem, but then bitrate was always set to 15...

Hi, I'm about finished developing a QuickTime component that supports Speex (on MacOS X and Windows).. As it is now the user can set complexity (SPEEX_SET_COMPLEXITY) and quality (SPEEX_SET_QUALITY / SPEEX_SET_VBR_QUALITY) and to wether to use VBR or not. Will these options make it possible to produce all combinations of bitrates/qualities? Or should I also use SPEEX_SET_MODE/SPEEX_SET_LOW_MODE/SPEEX_SET_HIGH_MODE to accomplish this? /Pontus --- >8 ----...

As for me - speex_echo_cancellation is a better choise. Try using it in capture thread instead of those speex_echo_capture and speex_echo_playback functions. And please, describe your problem in details. Cause the fact that you "didn get echo cancellation" doesn't mean you are doing smth wrong. Regards, Anton A.

Hi. I tried encoding a raw PCM file to Speex in my Windows Mobile device and it took about 45 seconds to encode a 10-second file. I had FIXED_POINT defined and used speex_encode_int. The device has an ARMV4 400 MHz processor. Question: Is this behavior expected or is it possible to encode speech to speex real-time such that I can record speech directly as speex in my device? What, if any, can be
