In a mono situation: a "frame" refers to the single sample for that channel. In stereo: a "frame" refers to 2 samples, one for *each* channel. So the difference between a frame and a sample is that a sample is literally a single data point, while a frame is a single "data point" for each channel. > Whereby one sample contains 2 frames. See above :) > CHANNELS = 2 > buffer_size_per_second = CHANNELS * 44100 * sizeof(signed short); Yep. The link below is useful for double checking, and for quick disk space calculations: http://www.sounddevices.com/calculator/ I've written a tutorial on using SndFile to write to disk: perhaps a useful resource to check / play with: https://github.com/harryhaaren/openAudioProgrammingTutorials/blob/master/writingSoundfileToDisk/writingSoundfileToDisk.cpp HTH, -Harry -- www.openavproductions.com _______________________________________________ Linux-audio-dev mailing list Linux-audio-dev@lists.linuxaudio.org http://lists.linuxaudio.org/listinfo/linux-audio-dev
