I will use it to make an MPEG file at that sampling rate. For large files, I may reduce the sampling rate for WAV files. Watch the oscilloscope display on the Goldwave display while you are recording. You can tell by watching if your level is too low or too high. Try to adjust the level so that you're filling up most of the available amplitude range without clipping.
Clipping appears as extended flat tops on the waveform.
Keeping the recording level as high as possible without clipping gives the recorded voice an advantage over quantization noise and other internal noise. Adjust the recording level so that you can get the mike close to your mouth without overloading. That gives your voice an advantage over ambient noise. Listen to the recording after you've made it. If you hear anything you're not pleased with, try to figure out what went wrong.
