![]() I have a couple waveform ‘design’ related questions. The background shows a spectral analysis for a the current play position with colour representing amplitude within each frequency band, not quite sure how to process that data to create colours on the waveform. I’ve been using Sonic Visualiser to study some tracks and see what various analysis plugins can do below is a veiw showing the waveform with beats and bars marked and numbered using QM beat and bar tracker. key analysis - Thsi would probably be a bar along the top of the overview showing changes in key - nalysed using QM Key analyser.Single line waveform - many programs displaying audio signals use a single oscilating line which when zoomed out gives the veiw normally seen.Spectral analysis for colour of waveform - mapped to wavelength of light, red low to blue high frequency (for colour of waveform - would not look anything like the barchart shown below thats just a visual representation of the data that would be used to produce it).Show bars as well as beats - using Queen Marys Bar and Beat tracker - there are anumber of possible ways this could be displayed.To zoom in on the wav, simply click the deck and use + and -.Īnother slightly hidden trick by holding the control button and clicking on a deck you can remove the color coding of the wave form, and split the view into 3 channels separate waves (hi, mid, lo) for an even more accurate picture into the mix.I’m thinking about creating a new waveform similar to that of Traktor and Serato. You can alter the wave form view in Serato as well but its less obvious. ![]() In Serato, they have colorized the wave forms to distinguish parts of the beat structure. ![]() ![]() In this image we are showing the same section using beats, beats & highs and beats + envelopes In Traktor you can choose how much of the wave form information is displayed to make the beats more defined and filter out non-rhythmic visuals. You can also customize the wave view to suit your personal tastes. How a program visualizes the wave forms is entirely up to them so several dj programs enhance the wave form views to make it easier for us to recognize these various parts. Now that a vocal is added, the frequency spectrum really starts to fill up.Īnd here in the break down there is a complete absence of loud transients (beats) In this section a synth stab is added and the wave starts to get more busy Notice that in this first wave form the space between beats is sparse, this suggests minimal instrumentation and a good place to mix. ![]() Its hard to separate the sounds visually from this view alone but with a little eye training you can begin to pick out some important trends and recognize various parts of the songs. The wider or longer the the wave length, the lower the frequency.Ī song is made up of many, many of these simple waves combined into one sonic image: The wave form you see above is expressing 2 fundamental things about one single sine wave, one of the most basic forms of sound.Ģ. Its really quite amazing that music, something we are so effected by, is really such a simple thing. In this article we will demonstrate the basics of the waveforms and show how 2 of the top dj systems Traktor and Serato enhance that information to make your job even easier. By watching wave forms you get an effective idea of what is currently happening and what is coming up so smart mix decisions can easily be made on the fly. A waveform is the play by play visual representation of the sonic action in a track. Digital djing provides a wide set of tools that make your job better but one of the clearest benefits is the ability to see each songs waveform. ![]()
