"Redundant audio data" header in speex payload
...? Is this header always present? Is its value always the same? Can it be modified through some speex_*_ctl function?

denoise.c missing from 1.1.4 archive
Hi, I just downloaded http://www.speex.org/download/speex-1.1.4.tar.gz and tried to build it but the file denoise.c seems to be missing from the archive. Can you fix this or is it better to get everything from cvs? Another question, when will a stable version of 1.1 be released. I'm interested in the preprocess features but I would also like a stable encoder/decoder :-) Best regards, Chris

SPEEX_GET_SAMPLING_RATE of encoder is wrong
Hi, I'm using speex 1.1.4 and when I query SPEEX_GET_SAMPLING_RATE as in speex_encoder_ctl ( m_pEncoderState, SPEEX_GET_SAMPLING_RATE, &m_SampleRate ); I get 2 The encoder is initialized with m_pEncoderState = speex_encoder_init ( &speex_wb_mode ); On the decoder side, the correct sampling rate is returned: m_pDecoderState = speex_decoder_init ( &speex_wb_mode );

Speex settings and jitter
Hi Conrad, Thanks a lot for the info. This is exactly what I needed. We want to use speex in our IP telephony client and I was indeed trying to put together a GUI configuration screen.

Fixed-point in CVS
Hi, Is there any speed advantage to using the fixed point version on a PC with an Intel or AMD processor? An advantage would be that you don't have to convert the audio input from short to float but what about encoding/decoding itself?

wideband bitrates
Hi, I found this list of Speex bitrates in the mail archive. http://www.xiph.org/archives/speex-dev/200306/0004.html Can somebody confirm that this list is correct? I am wondering about the following: - On the Speex website it says: "Speex is based on CELP and is designed to compress voice at bitrates ranging from 2 to 44 kbps." while the bitrates listed here are e.g. 84400 for

Speex preprocess & loudness
Hi, Does someone know if I could use SpeexPreprocessState::loudness or SpeexPreprocessState::loudness2 to create a VU meter.

RTP Payload Format for the Speex Codec
Hi, I have a few questions/remarks about the draft, in particular about the SDP usage of Speex (section 5): - Which samplerate should be used if you receive something like m=3Daudio 8008 RTP/AVP 97 a=3Drtpmap:97 speex/8000 a=3Dfmtp:97 sr=3D16000;ebw=3Dultra - There is an inconsistency in the description of the 'penh'parameter.

Size in samples of a Speex packet
Hi, Is there an easy way to get the size in samples of a Speex packet, without decoding the packet? If I receive a "narrowband packet" with - Zero or more wideband frames (must be skipped apparently) - Zero or more Speex inband requests - Zero or more user inband requests - One or more narrowband frames I need to know how much samples the packet contains to calculate jitter buffer

Performance increase?
Hi, I noticed that you changed all constant floating point numbers from double notation (e.g. 3.0) to float notation (3.0f) in the latest version of Speex (in subversion). Did that give any performance increase (because of elimination of the float to double and double to float conversions)?

Speex configuration
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 bitrate and

Speex settings and jitter
Hi, Is there are document where the interaction between all the configuration options of speex is explained? Speex seems to have CBR, VBR and ABR. You can also use SPEEX_SET_QUALITY (SPEEX_SET_VBR_QUALITY) and SPEEX_SET_BITRATE which I suppose can't be set at the same time. Is there a list of possible combinations somewhere? I also have another question related to jitter. To minimize jitter,
