Hi everyone,
I just released Speex version 1.0.1 with a major bugfix to the wideband
mode. It's highly recommended for people using wideband Speex to
upgrade. Also, since the old encoder and decoder had the bug, you may
notice that files encoded with 1.0 have a lower quality when decoded
with 1.0.1. For that reason, re-encoding might be a good idea. Note that
narrowband is not affected by that. Still, sorry for the inconvenience.
Otherwise, it's only minor fixes.

I am happy to announce that my ACM codec is nearing completion. Encoding works in NB / WB / UWB modes at 11 quality levels in both Mono and Stereo and 8 or 16 bit input resolution. So far I've put 3 straight evenings/nights of work into it (despite a day job). ;) Also I now have a command line speexdec version that decodes WAV files with Speex content. I am not yet sure if it would be wise to merge that with Jean Marc's speexdec. We shall see. I could provide a beta release the ACM codec today already... if only... well if only the decoding was implemented at this time. LOL. ;) Also I haven't decided on a final wFormatTag of the codec. Since I plan to author more than just this one ACM codec, I may simply "invent" my own Manufacturer ID and my own series of FormatTags ( somewhat above the range that Microsoft has assigned to avoid conflicts ). I doubt M$ would bother to assign a manufacturer ID to a hobbyist programmer via the offical contact address/phone #. Also on my list of are FLAC and Vorbis ACM filters. I seem to be getting "the hang of it". I may buy some commercial hosting and put all that stuff up on a site like www.openacm.org . I am pretty astounded by the quality that you can get for musical content in UWB mode (level 4). That's around 15 kbit/s netto. Most commercial streaming codecs sound much worse at that rate. hmm, 2 AM. Off to bed.

They are PCM, 16 bit stereo at 44100 Hz. What I'd like to do is make some "rule of thumb" tables for people to make guestimates about encoding with Speex, specifically regarding encoded file size vs content length. I won't be timing the encoding process because that is dependent on the available hardware. I'm by far no expert in audio recording/encoding/streaming/etc. so I'm not sure which settings can mix and which don't make sense used together. Does anyone have any settings they'd like to see results for right away (next couple days)? -- --Jeff Sr. Unix Systems Administrator & Engineer SAIR Linux and GNU Certified Professional This email may contain privileged and confidential information.
