Sound Detect

[iggy]

I'm looking for a command that allow my script to detect WHEN a sound is played.

(i tried with ProcessExists but i understand is wrong )

In the help file i only found command to play sound or change the volume but not for detect when is played.

I don't think you can do that with AutoIt since any application can talk to the sound card. AutoIt has no way of knowing what other programs are sending to the audio channels

Ok thanks

I am interested in the same general thing. I want to do something like poll the sound port(s) or monitor messages related to sound devices. I would like to activate Program B when, for example, audio output is detected, and deactivate Program B when audio is not detected for a specified time interval.

I have seen some commercial sound recording programs that monitor an audio channel and when the channel is active, it automatically records. When the channel is inactive, recording is paused. Does AutoIt have any hooks to these audio channels?

Might want to google that. You may be able to come up with a DLL solution that can get access to the sound in the way you are wanting. In AutoIt natively I dont believe there is a way.

Thanks. I suspect I can make use of Sven's script.

You could use winscope.exe (free and small) to detect line in sounds. your script would have to monitor winscope as to when it registered a certain amount of decibles. Its a work around..but perhaps it could work for you. Thought about this as a way to run a program based on decibel input. Like if my neighbors get too noisy, it would initiate a record sequence to record their noise and play it back through my huge speakers at ten times the volume with a three second delay.....

That would be great!!

im not sure how to do it! but im sure there is a way with a specifique dllcall from winmm.dll. search for api dll function MCI.

You just gave me an idea of a software version of a dog silencer where a high pitched sound, too high in frequency for humans to hear is used to blast a barking dog to discourage it from barking at inappropriate times. Now all I need is the API call to detect sounds and I should be able to get the sound card to play the appropriate WAV file at appropriate volumes on a spare set of speaker channels from my sound card and some outdoor speakers.

The only version of Winscope I have seen is 2.51 which is getting a bit dated and only supports 8 bit mode on sound cards. Has anybody had experience with using this on more modern systems such as XP with 5.1 and 7.1 channel 16/32/64 bit sound cards?

just thinking..i am not a programmer. However...Every sound forms a wave. Attack, decay,sustain and release. It you were to take a "picture" of that wave and be able to compare it and select a wave from a file on your computer that is the best match...would be ideal. I think that there is something in SDK voice recoginition that must be doing that. Gotta be some dlls out there for comparing waves or sensing volumes. I know there are many oscilloscope programs besides winscope. That worked for me for a while but crashes now. Sonic foundry is good for capturing wave forms. I just dont know if I could compare two waves , like you would do to pic files, to see if they are similar
