PCM (pulse code modulation) is lossy but not compressed. All analog to digital conversions are lossy. You can trade off sound quality against file size by limiting the sampling rate and the range and resolution of the samples. For example, the CD audio format samples at 44,100 16 bit integer samples per second in each channel (left and right).
