High signal-to-noise ratio
WebOct 1, 2015 · Essentially, this constitutes a high quality SNR. Bad SNR However, if your incoming audio signal is weak, it'll sit a lot closer to the noise floor. If you try to adjust the volume (gain) to increase the sound of your signal, the noise floor will rise with it. This would equate to a poor SNR.
