Audio Cleanup Examples:

These are some samples of our cleanup and restoration work. The clips contain the original audio followed by the processed audio. Each file has a description of the signal processing used.

Educational presentation in mid-sized conference room. Audio captured with video camera located near middle of the room. Processed with EQ and noise reduction.

- Presentation

00:00 / 00:00

Video interview recorded in a very reflective room. Processed with noise reduction, EQ and reverb reduction.

- Interview

00:00 / 00:00

Seminar in a noisy live room. Processed with low-pass and high-pass filters to reduce sibilance and stage noise . Noise reduction and reverb reduction applied.

- Seminar

00:00 / 00:00

Educational conference in medium-sized ballroom. Recorded with video camera near middle of the room. Processing included corrective EQ, noise reduction and reverb reduction.

- Conference

00:00 / 00:00

Old cassette tape. Processing consisted of filtering to remove excessive low-frequency content, adaptive filter to remove the L/R flutter and EQ to enhance the voice.

- Cassette

00:00 / 00:00

Surviellance audio. Equipment used to make the recording was of sufficient quality so all that was needed was a low frequency filter, amplification and a high frequency boost.

- Surviellance

00:00 / 00:00

Phone call. Because telephone audio is so band-limited, the goal is usually just to improve intelligibility. Processing includes equalization and high-frequency harmonics synthesis.

- Phone call

00:00 / 00:00

Electric guitar. '65 Gretsch that would not stay in tune. Processing included cut and nudge to tighten up timing, polyphonic pitch correction and amp sim.

Multichannel drums. Cut at transients and time align to grid. Click track left in for reference.

- Drums

00:00 / 00:00

Multichannel drums and bass. Drums cut at transients and time aligned to grid. EQ and saturation plugins applied. Bass cut and nudged to lock with drums. Click track left in for reference.
