Hi, Has anybody some information on on the "Redundant audio data" header in the speex rtp payload? Is this header always present? Is its value always the same? Can it be modified through some speex_*_ctl function? Thanks, Emmanuel -- ------------------------------------------------------------- Emmanuel Wauters Tel : (+32) 11 30 13 30

Hi, On http://www.speex.org/docs/manual/speex-manual/node11.html#SECTION001140000000000000000 the bitrate for Speex Wideband mode 9 and 10 is 9 34,400 10 42,400 On http://tools.ietf.org/html/draft-ietf-avt-rtp-speex-03 the bitrate for Speex Wideband mode 9 and 10 is 9 34.2 kbit/s 10 42.2 kbit/s I believe the draft contains the right values: E.g. mode 10 Narrowband mode 7 -> 492

Hi, No, it only happens with speex_wb_mode. But like I said, it is because in wideband mode, the function sb_encoder_init is called and this function initializes the sampling rate using speex_*de*coder_ctl instead of speex_*en*coder_ctl In narrowband mode, the sampling rate is just initialized to 8000 st->sampling_rate=8000; BTW, I saw that my email was added to an existing thread instead of

I'm using speex to encode wav files. How does the --bitrate n option (use bit-rate n or lower) afects the quality and time of the encoding? If I don't use that option how speex determines the bitrate to use in encoding?

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

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 );

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.

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? BTW, thanks for a great codec :-) Best regards, Chris <p>>> ----- Original Message ----- >> From: "Jean-Marc Valin"

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

Hi, Does someone know if I could use SpeexPreprocessState::loudness or SpeexPreprocessState::loudness2 to create a VU meter. And if so, how? <p>Thanks, Tom Moers --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list, send a message to 'speex-dev-request@xiph.org' containing only the word

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. According to the description,

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

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)? Best regards, Chris > When compiling in debug mode, I also get 530 warnings about double to > float

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

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,
