Slew Rate in Audio Amplifiers - What Does it Mean ...
https://www.audioholics.com/audio-amplifier/amplifier-slew-rate
Slew rate = Ipk/Capacitance So why do audio power amps claim a slew rate? Where is the capacitor? It is inside the amplifier. The slew rate is determined by the input circuit's ability to dump current into the Miller capacitance of the next amplifying stage. Bandwidth is an entirely separate issue.
Slew Rate - Audio Amplifier Design
https://renardson-audio.com/slew1.html
When audio amplifier slew rates are specified it is usually the 'large signal slew rate', and to achieve this the input stage needs to be driven close to clipping so that it drives the maximum current into the compensation capacitor. A typical arrangement is shown next, with a differential input stage driving a voltage gain stage with a ...
Measuring Slew Rate or Rise Time - Audio Precision
https://www.ap.com/blog/measuring-slew-rate-or-rise-time/
Slew rate is considered a large-signal performance measurement, as opposed to rise time which is a small-signal performance measurement. In both analog and digital amplifiers, the slew rate limit is generally set by the current available to charge or discharge capacitance in the amp or the connected output load.
Slew rate problems in switching audio amplifiers (class D, T)

Slew rate problems in switching audio amplifiers (class D, T) Premise . In electronics, slew rate is defined as the change of voltage or current, or any other electrical quantity, per unit of time. Expressed in SI units, the unit of measurement is volts/second or amperes/second or the unit being discussed, (but is usually expressed in V/μs).

It varies with the power or output voltage. The maximum slew rate at, say 200 Watts into 8 ohms at a maximum frequency of 20 kHZ is 7.1 Volts per microsecond. So anything that's closest to this number is the fastest for a 200 watter. If you're interested in the math: Vpeak = sqrt (200*8)*1.41 = 56.4 Volts. SR = 6.28 (20,000)*56.4/1000000 = 7.1.

Slew rate is simply measures the amplifier's ability to respond to changes in input signals , not just audio but also in industrial systems. ST says somewhere in its old TDA 20xx data sheets that too high a slew rate will cause problems. In audio systems, as a thumb rule, more than 12 or so is excessive.
Good Slew rate for audio | Microchip

The slew rate doesn't matter much for audio systems. The amplitude at the highest frequencies is orders of magnitude lower than at the lowest frequencies. Your peak slew-rate is probably in the mid-range, and probably on the order of mV/us max for a 3.3V single rail amp.

Since slew rate seems to be more a concern for power amplifiers, I calculated the slew rate for various power levels (rms) into an 8-ohm load and plotted it versus frequency below. The log-log plot presents the slew rate as a straight line at each power level (1, 10, 100, and 1k W).

Slew rate is the maximum rate of voltage change that can be generated by the op-amp’s output circuitry. It is measured as voltage relative to time, and the typical unit used in datasheets is volts per microsecond (V/µs). Let’s say you have an op-amp and apply an input signal that would, in an ideal environment, generate an output signal ...
