Linear interpolation sounds best when the signal is oversampled. Since natural audio spectra tend to be relatively concentrated at low frequencies, linear interpolation tends to sound very good at high sampling rates.

https://www.dsprelated.com/freebooks/pasp/Delay_Line_Signal_Interpolation.html
Delay-Line and Signal Interpolation It is often necessary for a delay line to vary in length. Consider, for example, simulating a sound ray as in Fig.2.8 when either the source or listener is moving. In this case, separate read and write pointers are normally used (as opposed to a shared read-write pointer in Fig.2.2).Additionally, for good quality audio, it is usually necessary to interpolate ...
Multi-channel audio upsampling interpolation - Signal ...
https://dsp.stackexchange.com/questions/58032/multi-channel-audio-upsampling-interpolation
Does cubic interpolation (or any other) have any advantages over linear for the specific case of audio? You'd use neither for audio. The reason is simple: The signal models you typically assume for audio signals are very "Fourier-y", to say, they assume that sound is composed of weighted harmonic oscillations, and bandlimited in its nature.

Bandlimited interpolation of discrete-time signals is a basic tool having extensive application in digital signal processing. In general, the problem is to correctly compute signal values at arbitrary continuous times from a set of discrete-time samples of the signal amplitude. In other words, we must be able to interpolate the signal between ...

If the input were an audio signal sampled at 48 kHz, the frequencies between 0 and 24 kHz would map to the frequency range on the graph between 0 and 0.25 (as we are interpolating by a factor of 4). At 18 kHz, we are attenuating the signal by about 11 dB; at 21 kHz, we are attenuating by about 31 dB.

precedes an ADC. The concept of oversampling and interpolation can be used in a similar manner with a reconstruction DAC. For instance, oversampling is common in digital audio CD players, where the basic update rate of the data from the CD is 44.1 kSPS. Early CD players used

Audio signals may be processed in a multitude of ways with the most familiar being equalizers which are also used on many car and home stereo systems. An equalizer processes the audio signal by increasing or decreasing the low-, mid-, and high-level frequencies to provide the most pleasing audio sound possible.
