Hi,

The RPi uses a simple crystal oscillator as a frequency reference when processing digital sound files. Would the addition of an accurate real-time clock (<1 minute per year) improve this situation in the hope of better sound quality or do RTCs only maintain time and date?

Many thanks.

The RTC would be connected to the Pi as a slave device via I2C or SPI, as such I doubt that they would be able to offer an improved frequency reference.
