Maybe function for playing different camera sounds can be useful for script writers.

PT_PlaySound(short sound, void* cb_on_end_of_play);
where cb_on_end_of_play is pointer to function (maybe void (void)) called on end of play or NULL,
sound is one of internal camera sounds:
0x2001 - startup sound
0x2002 - shutter sound
0x2003 - button press sound
0x2004 - self-timer sound
0xC211, 0xC20A, 0xC210 - short beep
0x400D - continuous "beeee"
0xC507 - ??
and experimentally found 50000 - AF confirmation

BTW, "my camera" sounds and startup image(s) stored in flash and can be easy extracted from firmware dump using hex-editor - at least for A-series cameras. Be careful and do not store private information there while dumping!  :D

Translation: Don't have your start-up sound event say something like, "For a good time, call (phone number)". :D


Yes. We should have a jokes section!

ewavr: is there an implementation yet? this would be really great! thanks.
maybe - and i do hope this will be possible - i can replace the UGLY "click sound" in videos when you take a photo. replacing it by a wav file with no data. funny thing is, in the s3is manual is stated that the audio clip during movie recording will not be interrupted when you take pics (opposing to the video of course) but this aint true (a loud CLICK sound is indeed an interruption, especially when you film a performance of classical music and take some pics during that).
looking forward to the implementation :)
keep up the good work!!!!

hm, i hate to say it: barney, i think you may be right about that :D
damn. so it's noise in my pictures and noise in my videos now :D darn. they could have at least muted the mic in the moment of shooting. it's really disturbingly loud. well yes, removing the noise afterwards is a good idea, have to edit the videos anyways(dramatically reduce in size, any tips regarding cutting down size without real loss of "information" using virtualdub? codec hints?) so i guess editing sound file isnt that a biggie. still sucks though.
haha funny, i just read your edit, should have read it earlier as i almost completely repeat your edit :D
yeah i have two cams now (well actually i lied all the time, the a620 wasnt mine, it was my girlfriend's :D) but bringing two (not really pocketsized) cams to a concert and a tripod, well, i suppose they wont even let me enter the event :D but for other things this will be the solution, yes :)

Ewavr, do you think you can turn this into an actual working function or tell us how we can do this ourselves (well, not me, but the more experienced ida cracks)?

thanks in advance, PhoX :)

what about the short "beep-beep" that the camera makes once video recording starts or when you half press the shutter? can that be disabled? I've disabled all sounds but I couldn't get rid of that

Turn on "Mute" function in camera menu (or hold "disp" button when camera powered-up).
