Fix issues with digital audio recordings.
The so-called Inter Sample Peaks are caused by faulty signal limiting during recording or intentional loud mastering. Some statistics state that around 80% of today's CD recordings show Inter Sample Peaks. A digital signal cannot exceed 0dB Full Scale but the analog signal, re-constructed out of the digital domain, is able to reach levels of +3dB, overloading heavily the Digital to Analog Converters (DACs) and therefore creating audible distortions. The AudioRepair tool is able to fix the Inter Sample Peaks by doing a 32 times up-sampling with a target sampling frequency of 1.4112MHz to simulate an analog signal for an accurate audio processing. The repair process adjusts the audio track level in a way that the resulting analog signal does not exceed 0dB to stay in the specification limits of modern DACs.
