Question

I need to convert some hi res audio files to u-law compression. I find no documentation on this- I'm almost certain the codec is there on Windows machines, but how the heck do I access it?

Was it helpful?

Solution

Not sure about the latter, however the first two have the μ-law encoder readily available (the codec itself has ACM interface, and DirectShow offers a wrapper over it).
