Neural networks create authentic digital models of analog amps

  • There’s no denying that vintage guitar amps sound great, but they can be huge, expensive and prone to frequent breakdowns.
  • A digital model of the target amplifier was created by measuring the circuit’s response to certain input signals and deep neural networks trained to emulate that amp.
  • The test subjects were played a reference clip followed by seven test clips from validation and test datasets through Sennheiser HD-650 headphones and asked to grade the accuracy of the timbre of the test tones against the reference tone.
