Ah, waveform drawing... From the looks of it, you're probably going to need to fork this and make your changes, because the FDWaveformRenderOperation doesn't support this style.

It looks like you can modify the plotWaveformGraph method in FDWaveformRenderOperation to achieve this. Currently, it iterates over every sample in the buffer, but if instead, you maintain an index that's incremented every nth sample (the bar "width") plus the bar "spacing," you can get this appearance. This is a naive approach, to be clear. Ideally, you'd average the samples in a "bar" and draw that value.

This is NOT compiling code, but should give you a place to start.

QUESTION

AudioKit, AKPlayer: How to play from Samples, not time

Asked 2018-Sep-12 at 01:00

I am currently using FDWaveFormView to great success to display waveforms representing audio I record from AKMicrophone or AKAudioFile.

I am successfully able to highlight specific regions in the waveform and FDwaveForm gives back a range of the samples from the audiofile.

My problem now is I cannot find an appropriate method in AKPlayer that would let me play from a start sample to an end sample.

I noticed that AKSamplePlayer is now deprecated, but it did have a method:play(from: Sample, to: Sample)

My guess is that I would be able to do some math to translate Sample position to time (as a Double as prescribed in AKPlayer), however I have not found the appropriate math or functions to do this, any hints?

To be very explicit in what I am trying to do, please refer to the image below:

note for any AudioKit core members who may see this question, I know there are a variety of AudioKitUI components that may of made this easier, however only FDWaveFormView has given me the functionality I need for this particular app, i'm happy to discuss further offline, thanks again so much.

EDIT

I've come up with some code that I believe has solved it:

This project's layout is based on https://github.com/fulldecent/swift4-module-template If you would like to change the layout, please change that project FIRST. Also you may appreciate that project has "recipes" -- you don't just change code, you also explain why you are doing things. As a maintainer this makes my job MUCH simpler. In a similar respect, if you are introducing non-minor changes, it will be VERY helpful if you could please reference to another project (like AlamoFire) that has seen and discussed the types of design challenges you are touching.) Thanks again and we all really do appreciate your contributions.
