Although the popular Cool Edit Pro has left the development as such (the program was bought by Adobe and now distributed as Adobe Audition) many people still make use of it for all kinds of adjustments to their audios. It appears to be a lightweight program but with multiple tools that can run perfectly on any PC.
Therefore, today we´ll begin to gradually see how this program works. And to start, we´ll learn a bit of its two editing methods: that of a single track (single waveform) and multitrack (multitrack mixer).
Single track edition
Through the track edition module we can deal with the audio files individually. Thus, we´ll work on the waveform (which is what we´ll see when we load the files to the program), channels and its basic parameters.
In this view we´ll see traditional playback controls (play, pause, stop, forward, etc) as well as typical editing actions (cut, copy, paste, etc.). In this way and through these commands, we can make changes in each channel very accurately, thanks to the zoom tools that help us get closer to where we want to be.
The most interesting part of this view you can find in the Transform menu. Here are some of the most interesting options:
- Invert: inverts the waveform horizontally
- Reverse: reverses the wave to be played from right to left (especially to hear the hidden or reversed messages in certain songs)
- Amplitude – Amplify: allows us to handle the wave amplification to increase it, reduce it, or apply fade in or out. Ideal to avoid saturations.
- Amplitude – Channel Mixer: in this case, the amplitude control is performed per channel.
- Amplitude – Dynamics Processing: amplitude control for audio marked with uneven volumes (the result of a bad recording).
- Amplitude – Envelope: Allows us to control the amplitudes by means of curves that limit the waveform.
- Amplitude – Normalize: leads to the peak of the wavelength (which does not saturate) meanwhile its full-length increases proportionally.
- Delay – Effects: here we find various effects such as echoes, chorus and reverberations, for modifying the audio so that it has more body and presence. Also, we find flanger and sweep type of distortions.
- Filters: multiple filters to retouch the bass, medium and treble frequencies.
- Noise Reduction – Click-Pop – Crackle Eliminator y Noise Reduction – Hiss Reduction: here we´ll find the necessary tools to eliminate any type of noise such as clicks, puffs, blows, etc.
- Special/Music: here we draw notes on a staff, which is subsequently applied to a section of the waveform to be adjusted to the height of such notes.
Ultimately, the single waveform is a tool that lets you control detailed settings for each track. Thus, you must work in a first instance so that potential problems of such files don´t get replicated and add up in the moment of joining them together en the multitrack project. In the second part, we´ll cover this second mode.
