From the developer:
BurnIn allows you to burn in your new headphones, earphones or speakers. It keeps track of the exact burn in time on multiple sets of speakers or headphones.
BurnIn plays White, Pink or Brown noise samples that are extremely "high quality" 16 Bit Linear PCM samples at 96000 Hz for best frequency coverage.
