SPEEX_SET_USER_HANDLER once again
Hi, Sorry! Marc Gimpel. I wrote it in a false thread before. It was my first time. :-) I have to write a small programm which should be able to record speeches and in addition synchronize the recorded speeches with measuring data. My idea is to record the speech in the normal way with speex and without ogg. If a sync message was received, i write a custom in-band messages using mode 13

SPEEX_SET_USER_HANDLER once again
Hi, I think what happened is that you did not write the "message" length. With user-callbacks, you also need to say how large the message. The size is in bytes and encoded in 4 bits. Besides, you're probably the first one to use user-callbacks. BTW, why didn't you want to use Ogg. It's much simpler to use and overhead can be made minimal anyway. Jean-Marc Le ven

I wonder what is correct. Inside speex the documentation was written that the size in byte is encoded within 5 bit. I changed the code in both ways, but it doesn't work

speed and memory
Hi Ulrich, I've never had any OutOfMEmoryExceptions in my tests, and I think I've been rather thourough, although probably much more thourought testing narrowband than wideband. Having said this, it is very hard to get memory leaks in java, so I am sceptical about that. That memory might not be used optimally is more likely the case. More often then not reducing memory use

herky-jerky audio
Just an update, and a follow-up question: I'm making progress on this issue, and will likely have something working very soon, now that I understand how the jspeex transcoding classes work. Unfortunately, I will need to make a couple small changes to the jspeex source code. My question is - is anybody using jspeex for streaming speex-encoded audio? It works great for static audio, but seems

jspeex question
The link is http://www.adobe.com/devnet/rtmp/. TC Message stands for TinCan message. It is 11 bytes long, first byte is message type, three bytes of payload length four bytes of timestamp and three bytes of stream ID. The first byte of the payload for audio message is the format byte and the rest of the byte is the payload. Jozsef ----- Original Message ---- From: Jeff Ramin <jeff.ramin

About reducing noise..
Hello, When I decode a recoded sound encoded by speex, it has too much noise. The noise is "slightly" reduced if I set the quality to 10. How do I get rid of this noise? The code is as follows. For encoding . state = speex_encoder_init ( &speex_nb_mode ); tmp = 7; speex_encoder_ctl ( state, SPEEX_SET_MODE, &tmp); // set quality tmp = 10; speex_encoder_ctl ( state,

jspeex question
FLV contains TC messages? TC message payload contains a format byte and speex frames (up to eight). In the format byte 0xb0 indicates speex. Speex is always 16 kHz, 16 bit, mono.

Need help in speex..
Hi, Vipin, What you're going to want to do here is convert your 8-bit stereo samples into 16-bit mono samples and back again when you're done(*). What you are actually doing here, it sounds like, is feeding 2 8-bit mono samples into Jspeex, which expects 16-bit mono. So, the most-significant-byte is in the right channel, and more or less gets encoded/decoded properly, but the

Real-time JSpeex coding
Hi, Is real-time possible with the current java-based JSpeex for real-time full duplex voice communication? If yes, can you please also provide some details of the Wintel (Windows on Intel) specifications that you have used to achieve that, and perhaps the JSpeex encoding/decoding specs used? Thanks. Cheers, Jo Yew Everyone should have a big dream and live a meaningful life to its

newbie qs. how to seek to a point in the Speex file?
Although this actually pertains to JSpeex, I am asking these questions here because they are general questions and also the JSpeex project does not seem to be supported any more. 1) Can the duration of the clip be stored in it? Page 24 here http://www.speex.org/docs/manual/speex-manual.pdf describes the format, but I could not see where the duration of the clip is stored. 2) Since the Speex

Calculate the audio duration of a speex file
I am having some trouble calculating the duration of my speex files. I am writing a speex player in Java and I am using the JSpeex port of the codec which works but doesn't give me the audio duration which I need to show progress or implement a scrubber. JSpeex appears to be all but dead but I don't see any other option for Java playback. I have tried the method posted here:

newbie qs - can one implement speex for Google Android?
I recommended in a bug report that the new mobile platform - Android should use speex and it was accepted. I was wondering if I can use it as a 3rd party library even now. Can someone please tell me how? The JSpeex project has had no activity for almost 3 years and questions are unanswered. the android post is here

Encoding/Decoding doubts
Flash player encodes speex at 16 kHz, mono, 16 bit. Fields in the format byte should be ignored if the format is speex. You can set the quality by Microphone.encodeQuality (default 6). You can also set the number of speex frames per tc message using Microphone.framesPerPacket. Flash player can only decode speex at 16 kHz, so make sure you have the proper sample rate.

Speex play back
I am a Java developer. I represent a small company writing a audio archiving application in Java using SPEEX files on Windows 2000/XP.
