Audio Op Amps - It's The Loop Gain You Seek, Not The ...
https://sparkoslabs.com/discrete-op-amps/audio-op-amps-gain-seek-bandwidth/
When choosing an audio grade op amp, some opt for high loop gain devices as it is well known that high loop gain makes for a more precise amplifier and lower THD specifications. Others decry the use of high gain devices, claiming the high gain …

Audio IC Op-Amp Applications. by Walter G. Jung. The application of the IC op amp to the field of audio signal process ing has been somewhat slow in developing. One reason for this has been insufficient treatment in technical books and papers of the problems the audio designer encounters when he attempts to in
operational amplifier - Which op-amp for audio ...
https://electronics.stackexchange.com/questions/8462/which-op-amp-for-audio
Op-amps have a gain-bandwidth product (GBW) which indicates that the bandwidth depends on the amplification; a higher gain (amplification) results in a lower bandwidth. GBW is closely related to slew-rate, and you want to have a much wider bandwidth than the 20Hz-20kHz of audio to get high slew-rate values.

Op-amps with bias-cancellation circuitry are normally unsuitable for audio use due to the extra noise this creates. The amount depends on circuit impedances, and is not taken into account in Table 4.1. The general noise behavior of op-amps in circuits is dealt with in Chapter 1. Op-Amp Properties: Slew Rate

An operational amplifier can amplify signals having a frequency ranging from 0 Hz to 1 MHz This means that OP-AMP can be used to amplify DC signals (0 Hz) as well as AC input signals (high-frequency signals). Furthermore, it is designed in such a way that external components like resistors, capacitors, etc. can be connected to its terminals.
Audio Designs With Opamps

Even the most basic types still have their uses in simple low-speed control circuits and other non-demanding applications. The operational amplifier was first used in the 1930's as the basis of analogue computers, and much development took place to design accurate gun aiming systems during the Second World War.

OP AMP APPLICATIONS 6.4 Electret Mic Preamp Interface A popular mic type for speech recording and other non-critical applications is the electret type. This is a permanently polarized condenser mic, typically with a built in common-source FET amplifier. The amplified output signal is taken from the same single ended
