sounding

A library for audio waveform manipulation

Installation

1. Add the dependency to your shard.yml:

   dependencies:
     sounding:
       github: aprildolly/sounding
   

2. Run shards install

3. Install libsndfile development files. The package name is usually libsndfile1-dev

4. Install rubberband if you want to use the pitch shifting or time stretching capabilities. You can either get the binaries here or install rubberband-cli via your package manager.

Usage

require "sounding"
include Sounding

#load sound from file
sound1=Sound.from_file("your_file.wav")

#create sound from slice
slice=Slice.new(3000,Int32.new(80000))
sample_rate=44100
channels=2
sound2=Sound.from_slice(slice,sample_rate,channels)


#superimpose multiple sound objects. sample rates are automatically changed to the first operand (in this case, that of sound1
sound3=sound1+sound2

#concatenate sound objects.
sound2<<sound1

#sample rates can also be changed manually. resampling is done automagically c:
sound3.samplerate=48000

#write sound to a new file
sound2.write("your_new_file.wav")
