How do you convert samples to time?

To convert the x-axis in the time domain you should have the sample rate of the signal. The sample rate is the number of samples per second and as the definition says, you have to divide the number of samples you have in the signal by the sample rate. Then you get the temporal length of the signal.

How to convert from sampling frequency to time?

The sampling period is the time difference between two consecutive samples in a Sound. It is the inverse of the sampling frequency. For example: if the sampling frequency is 44100 Hz, the sampling period is 1/44100 = 2.2675736961451248e-05 seconds: the samples are spaced approximately 23 microseconds apart.

How do you convert a sample to frequency?

Suppose this represents an audio signal that is sampled at 8000 samples/second. Then to convert f to Hertz, just watch the units: f [cycles/sample] × 8000 [samples/second] = 8000f [cycles/second].
