class Eagle::AudioBuffer

Overview

Decoded audio in memory: interleaved Float32 samples from -1 to 1.

A Sound wraps one. You deal with buffers directly only when generating or analyzing audio sample by sample.

.new(sample_rate : Int32, channels : Int32, samples : Slice(Float32))
Wraps existing samples.

#at(frame : Int32, channel : Int32) : Float32
The sample for channel at frame, with frame clamped to the buffer.
#channels : Int32
1 for mono, 2 for stereo.
#duration : Float32
Length in seconds.
#frames : Int32
Number of frames, where one frame holds one sample per channel.
#sample_rate : Int32
Samples per second per channel, such as 44100 or 48000.
#samples : Slice(Float32)
The interleaved samples: left, right, left, right for stereo.
