Mac Forum / Programming / Mac Programming / October 2005NSSound record?
Hi, I'm sure this has been asked many times but is there any sample code to record audio, into a buffer, using NSSound? NSSound seems to be only for playback. Can't find anything on Apple's website about Cocoa sound recording. Any help appreciated, thanks.

Can't find anything on Apple's website about Cocoa sound > recording. NSSound is only for playback, and Cocoa has nothing built-in for recording sound. Check out MTCoreAudio for a fairly comprehensive third-party audio framework which can feed you audio from an input device.  SignatureMichael Ash Rogue Amoeba Software Hi, Can I mix Carbon and Cocoa to record sound? I'm converting a project from Carbon to Cocoa and have sound recording working in Carbon. When is Apple going to get their act together about this? It seems pretty fundamental to me to have Cocoa sound recording. Thanks, Paul >> Hi, >> [quoted text clipped - 6 lines] > sound.

Carbon and Cocoa are just libraries, and you can use them both in the same application. There are certain limitations, like being unable to mix controls from the two within the same window (and if you go back to 10.1 and earlier, you can't mix Carbon and Cocoa events in the same app without doing some manual dispatching), but for the vast majority of stuff you can just pick up and go. > I'm converting a project from > Carbon to Cocoa and have sound recording working in Carbon.

Given the existence of Carbon APIs, CoreAudio APIs, and the very free MTCoreAudio framework, I see no particular need for a Cocoa API here. Cocoa apps can access the full set of libraries available on the system, so Cocoa doesn't have to provide absolutely everything itself.

No, that's just for playing. Recording can be done with Core Audio but I can't find any documentation for it. Try looking at /Developer/Examples/CoreAudio/Services/AudioFileTools/ Also, QuickTime 7 and up has built-in recording but I don't have the documentation here to find out where. Simon. Signaturehttp://www.hearsay.demon.co.uk No, never using Quicktime - got caught with that before with QT2. Need my own code so I'm hesitant to use MTCoreAudio as well.
