What is a buffering circuit? - University of Notre Dame
https://www3.nd.edu/~lemmon/courses/ee224/web-manual/web-manual/lab5/node6.html
A buffer is something that isolates or separates one circuit from another. In order to explain this more precisely, let's take a closer look at our 3-bit DAC. The 3-bit DAC constructed in the previous lab produced a digitally controlled voltage, but it turns out that we can't really use this voltage as a source to drive other circuits.

A unity-gain, standalone buffer circuit First, despite which IC is used for U1, close attention should be given to making buffer stages free from parasitic effects, at both input, output, and supplies. Physical construction of buffer-drivers and other high current stages should be in accordance with high speed rules.

Audio Preamplifiers Audio signal preamplifiers (preamps) represent the low-level end of the dynamic range of practical audio circuits using modern IC devices. In general, amplifying stages with input signal levels of 10mV or less fall into the preamp category. This section discusses some basic types of audio preamps, which are:

audiocore. – Support for audio samples. Create a RawSample based on the given buffer of signed values. If channel_count is more than 1 then each channel’s samples should alternate. In other words, for a two channel buffer, the first sample will be for channel 1, the second sample will be for channel two, the third for channel 1 and so on.
operational amplifier - how to split audio with buffers ...
https://electronics.stackexchange.com/questions/197827/how-to-split-audio-with-buffers
I am split an audio signal coming from an op amp to both a line driver buffer and a VU meter buffer, as shown in the schematic. My trouble is in determining the correct placement and value of resistors R1 and R2 in order to split the audio signal without affecting the level.

An audio circuit collection, Part 3 Introduction This is the third in a series of articles on single-supply audio circuits. The reader is encouraged to review Parts 1 and 2, which appeared in the November 2000 and February 2001 issues, respectively, of Analog Applications Journal. Part 1 concentrated on low-pass and high-pass filters.
