Re: Beep ( duration, frequency )

If there is only a small selection of frequencies and durations your app need to play, you can pre-record them as audio files and play them back when required. If it’s something like an instrument or requires procedurally-generated audio, you may want to package the sound effect you want into a

[ALERT:Possible Phishing] Re: Beep ( duration, frequency )

There is also AVAudioEngine added in Yosemite. It's a higher level Objective-C API around Core Audio. The docs still kind of don't tell you much and at times the API makes more sense if you know a little about Core Audio but the friction is a lot less C level. The Amazing Audio Engine is a fa

Re: Beep ( frequency, duration)

The following plays a 441 Hz tone directly into the audio driver. If you alter this code, it is important not to block requests from the audio driver for more samples. While this source runs in userspace, and it supplies data from userspace, the requests for samples seem to be coming from a hardw
