Now, I’m not saying that you’ll be able to read words, but you’ll start to pick out some of the more obvious sounds, transients, and phonemes with a bit of practice. Spectral frequency adds audio frequency range to the view. The brighter the color, the louder the sound, so cross-referencing bright and dark areas against the frequency axis will give you a surprisingly good idea of the sound being made. It plots time (x) against audio frequency (y), and the colors are just a heatmap that shows how loud the sound is at a given frequency. Spectral frequencyĪt first glance, the spectral frequency display (Shift+D) can be intimidating, but it’s actually pretty simple. But the chances are that you’ll spend most of your time with the waveform view minimized to give the spectral frequency more room, which you can do by dragging the horizontal divider up and down to suit. But it’s still useful to check for instances of audio clipping, or creating fade envelopes, or seeing how much headroom might be available for gain or compression. Once you get to know the spectral frequency display a bit better, you’ll probably rely on the waveform view a lot less. The waveform shows amplitude against time. Just as with the Levels meter, this is measured in dBFS (decibels relative to full scale) with a maximum peak of 0dBFS. This is the simplest and most familiar of the two and is time (x) plotted against amplitude (y), with peaks indicating loudness. So before we get down to the specifics of editing and cleanup, let’s take a look at the displays you’ll be using in post- waveform and spectral frequency. It’s not your only option, and a lot of the features noted here can also be found in other applications, so you should be able to follow this guide even if you’re using a different editing tool.Īdobe Audition is a powerful audio editor, and like most of its type, the extent of its feature set can make it intimidating to the newcomer (or even a video veteran who’s never seen a spectral frequency display before). And for this, we’ll be staying in Adobe Audition. This entry was posted in Tutorials, Wavosaur on 27 September 2013 by Wavosaur.If you’ve been following this four-part series, then you’ll know that we’ve already covered choosing your microphone, preparing your environment, and recording your voiceover. In Wavosaur you can use VST filters plugins to lowpass your song, there are also native filters : menu Effects -> FilterĬhoose low pass and experiment with a frequency cutoff around 200 Hz (and large Q ). Nothing prevents you from filtering your song to keep ONLY the bass sounds (just cut to a frequency lower enough to not hear the voice) and then mix this filtered sound with the “mono removed” file, then you can get back some of the lost bass sounds from the mono removing. It’s the case with the bass, the kick drum… Often, the lower sounds from the spectrum are mono in a mix, so they disappear after a “vocal removing”. Modern recordings tend to give unpredictable resultsĢ) load wav or mp3 file of Elvis Presley – Stuck On You That’s why this method works better on old recordings, with very hard panning, and not-too-much effects on voices. The voice has to be dry, the more it’s affected with effects like reverb, chorus, delay/echo, the more you’ll get the “voice presence” after a voice removing.Īlso don’t forget that ALL mono sounds will be removed ! if the bass is mono : cancelled, if the kick drum is mono : cancelled ! Of course, the more the voice is MONO, the more it works ! The “vocal remover” option in Wavosaur do this : it inverts one channel, mixes the two channels into one channel then copy this channel (so you have two channels, but with a mono sound). The guitar stay “negative” but it just mean a 180° phase shifting, something you don’t notice, the vocal is cancelled When you mix the two channels you have : vocal – vocal + battery – guitar = battery – guitar When you invert/flip left channel, you have : – vocal – guitar To make it simple imagine you have a song with this configuration : Yes, nothing is left when you sum the two channels.
