What is an audio buffer? – PS Audio
https://www.psaudio.com/askpaulvideo/what-is-an-audio-buffer/
The output current might well be larger than the input current, but the buffer isn’t a current amplifier because it doesn’t generate an output current that is a precise larger version of the input current. By contrast, a current amplifier with a gain of (say) 10 would take an input current of 1 mA and generate an output current of 10 mA.
Audio Designs With Opamps

A very common opamp application is the buffer stage, which (for the non-inverting configuration) can have an extraordinarily high input impedance, and a low output impedance. As with all opamp circuits, the output impedance may be very low (typically < 10 ohms), but the output current capability will not allow the circuit to drive such an impedance at more than the 20mA or so …

The buffer output impedance is essentially resistive (10Ω) and maintained constant up to 2MHz, as shown in Figure 3. This includes the series resistor R12 (5Ω). The series resistor may prevent parasitic oscillations with the capacitive loads. The noise voltage spectral density shown in Figure 4 is equal to 1.7nV/√Hz at 1kHz.

The resistor values depends on the amplifier's output. The idea can be accomplished fully by amplifiers, yet, the schematics show the transistor approach. Some explanations : I discussed the difficulty to make an equal control of …

Let a simple concept of an audio amplifier is to be designed like this (in BJT) : CC *CE* CE * OUTPUT .... and CC acts as a buffer. Why does a buffer is required for the amplification? Wouldn't it be much more simpler if CC is being cancelled out? CC = Common Collector CE= Common Emitter Thanks in advance! Answers and Replies Nov 13, 2011 #2

However, simply buffering the amplifier's output with an isolated-package circuit removes this source of error, and maximizes op-amp linearity. This step is recommended wherever it's practical and...
