Click Removal is designed to remove and minimize short clicks and crackles that are often found in audio recordings made from LPs. The Click Removal module is not intended to remove long "scratch" noises. However, it can remove short scratches not exceeding 3 ms. in length.

The Click Removal dialog box is shown below.

Noise Removal is designed to minimize or fade stationary background noise with a constant level and frequency, such as tape or microphone hiss, powerline noise, or drive motor hum. The Noise Removal algorithm is not intended to remove non-stationary background noise, such as quiet background speech or the sound of running water.

The Noise Removal dialog box is shown below.

Hiss Removal is designed to remove and minimize background hiss that is typically found in tape, LP, and possibly microphone recordings. This algorithm does not require a sample of pure noise (noiseprint). You can use this module when your recording does not contain fragments of pure noise, or when the application of Noise Removal is not satisfactory. The Hiss Removal algorithm is not intended to remove non-stationary background noise (e.g. quiet background speech, sound of running water, etc.) or noise other than a typical hiss (e.g. powerline noise, drive motor hum of equipment, etc.).

The Hiss Removal dialog box is shown below.

The Total Recorder Audio Restoration Add-on requires registration. The evaluation copy is a fully functional version of the program with the exception that an audible noise will be inserted about every 60 seconds throughout each recording. For unlimited recording without the insertion of an audible noise, you must purchase a license for the Audio Restoration Add-on.

Note: The Total Recorder Audio Restoration Add-on Version 1.2 requires that you install Total Recorder Version 7.0 or higher.

Beginning with version 1.1, the Audio Restoration Add-on uses a new format for the registration key. If you are a registered user who wants to upgrade and you did not receive your new registration key, use the self-service registration key management system or contact support@totalrecorder.com.
