@ustk Thank You

Im going to script a custom drop panel that will feed an audio file into an audio player. Atleast thats what I think I should do? Then run your script either in a button or inline my DROP script to run automatically. Am I right so far with using an AudioPlayer for that?..because I know we can just read the file AND load the audio file for auditioning at the same time, right?

@Chazrox no need for a audio player for a simple playback you can just use Engine.playBuffer()

[ustk]

@Chazrox Yeah AFs in Hise can be fetched from anywhere, AudioPlayer, Scriptnode, Sampler, etc...
The methods can differ but I imagine there are some examples in the doc and the snippet browser

[Chazrox]

@Christoph-Hart hmm! I def have some reading to do. This is exciting. Anything you can recommend I read in documentation?

@ustk speaking of 'methods' im investigating and got these...

  {
    "normalise": Method,
    "toCharString": Method,
    "detectPitch": Method,
    "indexOfPeak": Method,
    "toBase64": Method,
    "fromBase64": Method,
    "getMagnitude": Method,
    "getRMSLevel": Method,
    "trim": Method,
    "getPeakRange": Method
  }

All new to me but looks promising!

I have no idea what "Method" is referring to tho. Never seen this before.

@Chazrox start from here:

HISE | Scripting | Buffer

A buffer of floating point data

(docs.hise.audio)

[Chazrox]

@Christoph-Hart Thanks! Reading that now.

Sorry if this is an irrelevant question, but how can we use this with online processing?

For example, online pitch detection?

[Chazrox]

@resonant i'd like to know that too haha.

[Chazrox]

@resonant do you already know how to do offline analyzing?

No I don’t know how to do that. But I’d really like to know real time spectral processing with Hise.

@resonant

C++ nodes can do it.

C++ nodes into c++ graphics.
