THG's Secret Test Sauces Revealed

CoolEdit Pro 2.1

This program normalizes audio files to bring several files to a uniform volume level. For MP3s, the program MP3 Gain is recommended.

CoolEdit is an audio processing program, and, depending on the process, demands a hefty share of computing power. Normalizing music files is just one practical application for this program, but one that can be used to good effect in benchmarking. CoolEdit is thread-optimized, so that with Hyperthreading and future generation dual-core processors there is a definite increase in efficiency.

Installation

CoolEdit is not free. After installing, you have to register it with the manufacturer using a registration tool. Only then can you update to Version 2.1.

Settings

When starting the program for the first time, switch to the Single WAV mode by clicking on the button in the top left-hand corner.

Benchmarking

Open a wav file via 'File » Open...'

The normalization process starts under 'Effects » Amplitude » Normalize...'. Unfortunately, CoolEdit doesn't display how long the process takes, so you have measure the time yourself.
