Am looking for an Mono Channel Audio Amplifier which can accept inputs from SAI interface and play the content on 30W loudspeaker. Amplifier should support for adjustable gain, as we want to compensate external noise(sound). And should support for maximum SPL of 95dbm.
Could anyone please suggest an Amplifier and an technique to measure the ambient Noise (Sound) level which could suit out application. We dont want to use any codec in between. As our recordings are *.wav files.
