I'd do this last to compensate for any level loss due to EQ and compresssion. This will adjust the overall volume level of the track, leaving you with ample headroom. (Sorry, can't remember offhand if Audacity includes a spectrum analyzer.)įinally, I'd normalize the track to -3 dB. A spectrum analzyer can also be very helpful in finding hiss and noise, you can then target and EQ out the noisier frequencies. A special 'curve scale' feature which amplifies the overall frequency response. Mouse drag modifier for even more precision. Accurate curve UI with an dB axis zoom feature for extra precision. Additional Low pass and High pass filters for bass/treble roll off. However, I would be careful particularly if there is any background noise - if you've ever watched a war movie on DVD and struggled to hear the voices over the explosions even though the voices were perfectly audible during the quiet scenes - well, that's compression doing a bad thing.ĮQ and compression are going to be pretty much trial and error, keep playing around until it sounds good to you. Paragraphic equalizer with 7 bands, with the option of bell, high and low shelf shape. Compression will level the volume over the selected area at the expense of dynamics - for this kind of thing I imagine that you should be able to get away with quite a bit of compression. If the volume is inconsistent, I'd try my luck at some compression. Similarly, you can probably roll off anything on the low end below 500 Hz, but this will probably be much less noticeable. That being said, I would probably start by using the equalizer to eliminate the high end anything you picked up on the phone over 5 kHz is probably noise. I often use Audacity at the beginning and ending of a project, but I add all my cool effects using other programs. The biggest drawback in Audacity is that you can't adjust effects while you are in playback mode you have to apply an effect over a time range, and then listen to your clip to evaluate the results.
