Low w-ESR capaccitors are an n ideal selecttion, and a value v of 1μF F is typical.

For filtering lowe er-frequencyy noise signa als, a 10μF or o g greater capaccitor placed near n the audio power amplifier would also help, bu ut it is not req quired in mos st application ns b because of th he high PSRR R of this devvice.
