Details

This method provides a wrapper for the tuneR::writeWave method from tuneR::tuneR. It also provides the means to export audio to file formats native to the Commodore Amiga. PTSamples can be exported as simple (uncompressed) 8svx files also known as "iff" files). In addition they can be exported as raw data, where each byte simply represents a signed integer value of the waveform.

Examples

data("mod.intro")

## Export the second sample of mod.intro as a wav file:
write.sample(PTSample(mod.intro, 2), tempfile(fileext = ".wav"), "wav")

## Export the second sample of mod.intro as an 8svx file:
write.sample(PTSample(mod.intro, 2), tempfile(fileext = ".iff"), "8svx")

## Export the second sample of mod.intro as a raw file:
write.sample(PTSample(mod.intro, 2), tempfile(fileext = ".raw"), "raw")
