A few years ago, I generated two WAV audio files at 44.1 kHz sample rate using Audacity. I used these audio files to assess various equalizer VSTs in Mixcraft. The audio files are:
1. White noise
2 A series of sine tones at 50, 100, 200, 400, 600, 800, 1000, 2000, 3000 4000, 5000, 6000, 8000, 10000, 12000, 14000, and 16000 Hz
I loaded these audio files into Mixcraft 8 build 418 (64 bit), and a copy of Ableton Live 9 Lite version 9.7 (32 bit). I put a copy of SPAN on the Master bus. NO other VSTs of any variety were present.
The white noise file should generate basically a flat line in SPAN (slope set to 0 in the spectrum mode editor) and the peaks of the sine tones should also form a flat line in SPAN for the same settings. The results are shown in the graphics below.
Mixcraft 8 and Ableton Live 9 Lite generated the same SPAN graphs. Both showed slight non-flat behavior, but identical slight non-flat behavior.
Conclusion: The audio engine performance of Mixcraft 8 and Ableton Live 9 is identical.
I will hypothesize that all DAWs will produce the same result with the same audio test files and same test method. I will leave it to others to test their DAWs. The white noise file is easy to generate with Audacity. The multi sine tone file is more difficult to produce, and is attached in a zip file.
The sound processing VSTs applied between the raw audio and the output of the Master bus are the most likely sources of audible differences between identical audio sources.
Excellent, thanks for sharing this.
