Later I've modified a2play so it can play pre-encoded sbc (sbcend output) to skip encoding part, but it still far from what I get when run it on PC. I think there is a synchronization problem somewhere there, hear a lot of clicks, drops and repetitions. I've tried it with 2 different pairs of headphones, on Bluewalker and on HP's (iPAQ gadget), and while the former sound not extremelly bad, the latter sound very crappy (there are periods when they sound ok, but mostly they are out of sync?). So it looks like it somehow connected with how the headphone handle timing? I have a couple of questions: 1) Is there anyone buse with sbc fixed point convertion? 2) Is there anyone with similar problems (out-of-synch sound) and knows how to solve it (or is it just about tuning the timer?)? Thanks in advance. Regards, Victor. P.S. I run the same code on PC it sounds good, so should be something to do with switching platforms? -----Original Message----- From: bluez-devel-admin@lists.sourceforge.net [mailto:bluez-devel-admin@lists.sourceforge.net] On Behalf Of Brad Midgley Sent: Wednesday, June 15, 2005 19:50 PM To: bluez-devel@lists.sourceforge.net Subject: Re: [Bluez-devel] Advanced Audio Distribution Profile (A2DP) Claudio, What is it you want to do? We have prototypes for sending and receiving a2dp. For the desktop, we need to adapt the a2dp sender to be an alsa plugin. Marcel has done some work on that. I've been trying to slim down the floating point operations in the sbc library so the thing will run on an arm cpu. see http://bluetooth-alsa.sf.net Brad Claudio Takahasi wrote: > Hi folks, >=20 > Is there anybody working on Advanced Audio Distribution Profile (A2DP)? >=20 >=20 > What are the available tools and software for linux/Bluez that provide > audio streaming? >=20 >=20 >=20 > Claudio. >=20 >=20 > ------------------------------------------------------- > SF.Net email is sponsored by: Discover Easy Linux Migration Strategies > from IBM.
