Noise generator
White, pink and brown noise for system alignment, room checks and masking.
Pink noise is the standard signal for room and PA measurement: its spectrum matches how we perceive loudness across octaves. White noise sounds brighter and puts more stress on tweeters.
How it works
White noise has equal energy per hertz, so it looks flat on a linear scale and sounds bright. Pink noise falls 3 dB per octave and has equal energy per octave: it looks flat on a real-time analyzer and is the standard signal for tuning PAs and rooms. Brown noise falls 6 dB per octave.
