Efficient method to draw a line with millions of points
Can anyone please help me with displaying the waveform of an audio file in xcode?
Actually, I've recorded an audio through AVAudioRecorder class. Now, I want to get the waveform of this either while the audio is being recorded OR use the .caf file it saved.
Please?
Thanks :)
