With tape, a single-edge razor, and an aluminum cutting block. Yes, audio editing prior to the Mac was accomplished by good old manual labor. Today, audio can be recorded, editing, sweetened, and repaired in minutes on a number of great Mac apps. Here’s a good one and it’s free.
Recording & Editing Today
Every Mac, iPhone, and iPad comes with a very capable audio recorder in Garageband. It’s multiple track, high quality, and professional level.
Editing audio on Garageband– slicing and dicing audio waveforms to eliminate bad recording and to piece together a finished product– is anemic at best.
One of my favorite Mac audio editors is Amadeus Pro, a well designed, dependable and feature rich app which has been around for years.
It’s very good, highly recommended, but not free.
If your budget dictates free and Garageband doesn’t give you the editing flexibility you want, try OcenAudio. It’s free, very good, and cross platform– Mac, Windows PC, and Linux PC.
OcenAudio is at once familiar and instantly usable to record audio and edit audio waveforms.
Features include multiple EQ options, gain and audio filtering– all done in real time preview. Adjust the controls, hear the sound changes.
Effects and filters can be applied to multiple selections on the waveform, a first for me. This is a good way to enhance a weak audio signal during an interview.
Also included in OcenAudio is a very good audio spectrogram, which lets you analyze the audio to isolate specific sounds to edit.
Transport controls are easily accessed, filters, effects, and enhancement options are many, and OcenAudio can handle VST plugins, too. The app can record audio using the Mac’s standard audio input options (and playback output options). Simply click the red Record button.
The free and cross platform Audacity app has a few more features but has never been as stable for me as OcenAudio which can handle very large audio files with ease.
