Peak – Definition
A peak is the highest instantaneous level reached by an audio signal during recording, playback, or mixing.
What is a Peak?
In digital audio, peak levels are measured to ensure that the signal does not exceed 0 dBFS (decibels relative to full scale). If a signal rises above this limit, digital clipping occurs, producing unwanted distortion. Peak meters in digital audio workstations (DAWs) display these maximum signal levels in real time.
Monitoring peak levels is essential for maintaining clean recordings and preserving audio quality throughout the production process.
How is Peak used in piano recording?
Pianists recording acoustic or digital pianos should monitor peak levels to avoid clipping during loud passages. Setting an appropriate input gain provides enough headroom for dynamic performances while maintaining a strong, distortion-free signal.
Understanding peak levels helps musicians produce cleaner recordings and achieve professional audio quality.
