Restoration

Azimuth

Azimuth is a phase correction tool that can compensate for phase errors in tape recordings that were caused by different gap widths between recording and playback.

These phase errors are often the reason for a loss of high frequency information in monosummed signals and detail in the stereo panorama. Azimuth automatically detects and corrects these phase errors with a precision of one twenty-fifth of a sample.

Audio Example

Here you can listen to sample files, before and after the automatic restoration. In this sample there are 4 parts of each 5 seconds. The first part is the original audio material with the azimuth error, the second the restored material. The third part is the mono sum in original and the fourth part the mono sum restored.

• Tape Azimuth error - Original stereo
• Tape Azimuth error - Corrected stereo
• Tape Azimuth error - Original mono sum
• Tape Azimuth error - Corrected mono sum

In addition with Cube-Tec's AudioCube - Azimuth, detailed presets for specific audio problems can be created and used for the DOBBIN system. Have a look at the AudioCube - Restoration VPI Azimuth.

DeClicker

The DeClicker removes separately perceptible clicks from audio recordings. No sound coloration will occur during processing; the signal does not become dull or hollow and the auditory space of the recording is maintained.

Audio Example

Here you can listen to a sample files, before and after the automatic restoration. In this sample the DeClicker and the DeCrackler has been used.

• Vinyl with clicks and crackles - Original
• Vinyl with clicks and crackles - restored

DeClipper

DeClipper is used to recover the loss of peak signals due to clipping from recording over full-scale digital.

In combination with the LoudnessOptimizer the declipping can happen with nearly no loss in dynamic of the audio material.

DeCrackler

The DeCrackler has been optimized to remove up to 8000 disturbances per second. The latest adaptive algorithms have been employed, significantly simplifying user operation.

Audio Example

Here you can listen to sample files, before and after the automatic restoration. In this sample the DeClicker and the DeCrackler had been used.

• Vinyl with clicks and crackles - Original
• Vinyl with clicks and crackles - restored

DeNoiser

The DeNoiser is a broadband, single-ended noise reduction tool that is optimized for tape-hiss removal.

Audio Example

Here you can listen to sample files, before and after the automatic restoration.

• Tape Noise - Original
• Tape Noise - restored

In addition with Cube-Tec's AudioCube - DeNoiser, detailed presets for specific audio problems can be created and used for the DOBBIN system. Have a look at the AudioCube - RestorationVPI DeNoiser.

DeScratcher

The DeScratcher is used to resolve large scratches up to 1000 samples. Transient disturbances with a length of more then 30 samples demand different audio algorithms than short crackles. DeScratcher is optimized to carefully remove large scratches without destroying the audio program.

Audio Example

Here you can listen to sample files, before and after the automatic restoration.

• Vinyl with large scratches - Original
• Vinyl with large scratches - restored

In addition with Cube-Tec's AudioCube - DeScratcher, detailed presets for specific audio problems can be created and used for the DOBBIN system. Have a look at the AudioCube - RestorationVPI Descratcher.

PlaybackEQ

The PlaybackEQ is one of the first tools for the DOBBIN system, that can be used for automatic restoration of audio. All DOBBIN Restoration FPU's are based on twenty years of restoration experience, refined and optimized for mass audio file processing.

The PlaybackEQ VPI precisely emulates the analogue circuits of 20 different playback equalizer transfer functions, including RIAA/CCIR, all the different NAB and IEC curves, and numerous others.

Apart from the obvious, there are numerous additional applications for the 'Playback-EQ'. Have you ever wondered if a tape was transferred using CCIR EQ when the NAB curve really should have been used? Do you have some "safety" masters in your archives that were incorrectly identified and copied as RIAA when they were actually flat?

In the past, these have not been easy to check/correct in the digital domain, because no digital EQ was able to accurately reproduce the playback curve characteristics of the analogue pre-amps that have been used at the time. The PlaybackEQ VPI now makes this possible, through amazingly accurate modeling of the original playback equalizer transfer functions.
