Audio Precision’s ATS-2 and 2700 series analyzers can make all of these measurements. SNR is available using a Quick launch macro, dynamic range measurements rely on the THD+N amplitude function meter, and noise in the presence of signal measurements can be made using our multi-tone analyzer.

Record the audio signal with a digital audio interface (if you're using a laptop, unplug the AC adapter and power it from battery, to avoid the typical 50 Hz noise and other power supply noises) Stop the playback of the sine and also record some silence (and thus some microphone noise: that is precisely what we want to measure!).
S-Meter - Software-defined Radio

S Meters can display not just the signal level, but also the Signal to Noise Ratio (SNR) which is often more meaningful. Note: When no signals are present with the SNR display it is quite normal to see a SNR reading. This is because Noise is the mean (average) whereas Signal is the peak value, so even in a quiet part of the band there will be a difference between the peak and mean.

https://electronics.stackexchange.com/questions/603414/acceptable-snr-for-a-sound-level-meter
Acceptable SNR for a Sound Level Meter 0 I'm designing a low power (<150mW) sound level meter (SLM) using a 24bit ADC (preliminarily using the LTC2512-24 ). This is for audible frequency range signals only (20Hz - 20kHz).

Weighting filters are normally used with acoustic noise measurements, to simulate the response of the human ear. For amplifier signal-to-noise ratio, you measure the noise in the relevant bandwidth (probably 20 kHz for an audio amplifier) and compare it to the maximum amplifier output or to the typical amplifier output, as required.
