Description

In signal processing, sampling is the reduction of a continuous-time signal to a discrete-time signal. A common example is the conversion of a sound wave to a sequence of "samples". A sample is a value of the signal at a point in time and/or space; this definition differs from the term's usage in statistics, which refers to a set of such values.

A sampler is a subsystem or operation that extracts samples from a continuous signal. A theoretical ideal sampler produces samples equivalent to the instantaneous value of the continuous signal at the desired points.

The original signal can be reconstructed from a sequence of samples, up to the Nyquist limit, by passing the sequence of samples through a type of low-pass filter called a reconstruction filter.

Converting to A-Law 16 Bit ?

I have a question consirning audioconverting.
Does anybody know if it is possible to convert a .WAV 44.1kHz. 16Bits Mono file into a A-law 8 kHz. 16Bits Mono file?
Normally I convert the WAV's into A-Law 8 Bits, but now I need to convert them to 16 bits files which seems not possible with the programs I use.(Soundforge 4.5, Wavlab 3.0, CoolEdit)
