You may want to check out the source code for Audacity (http:// audacity.sourceforge.net/) for an example of how they do waveform drawing. Of course if you are creating code for commercial use be careful how much code you borrow, as Audacity's creative common license (http://creativecommons.org/licenses/by/2.0/) has some restrictions.

Also for dsp you can check out musicdsp.org for a nice set of free dsp algorithms.

I've done the waveform display thing, I like to interpolate by taking the highest sample-value per pixel bin. Not perfect, but it generally gives pretty good looking results.

I was thinking about some sort of heap-structure to optimize for resizing of the display, any ideas on that front? Looking at megs of samples is a drag when you're just trying to resize the display.

For DSP intro's, I recommend the Electronic Music Tutorial by Curtis Roads. It's a long read, but very thorough on a whole lot of topics.

Hi,

Can anyone suggest a book on CoreAudio or additional documentation -- other than the official Apple stuff that I can read up on? Also, does have any advice on general DSP books? I need to read up on things like rendering waveforms as images fast. It is really hard to write code to show a waveform in 1000 pixels when the source material is several megabytes. There must be some standard industry books on routines and examples on how to do that sort of thing? no? I am a long time programmer, but really new to audio stuff, so I am kind of a newbie.

Thanks.

John
