Hi all, While hacking around with aliasing effects in digital compressors (Yes it is real, yes you can hear it!), I happened to run a 10Khz sine wave into jamin with an instance of Jaaa hooked up to the output. The results were 'interesting' as it appears that jamin introduces easily measurable harmonic distortion even with all compressors and eq bypassed! Switching the master bypass in jamin however does make the effect go away. This was at a level of -26dbFS with no boost and with the limiter bypassed. I say 'harmonic distortion', but it really is not quite that as it appears as a series of narrow spikes every few hundred Hz. Further checks show that the same effect appears with the test tone turned down to 2.5Khz and that eq bypass has no effect. Now with a single tone we are looking at per 'harmonic' energy almost a hundred db down on the test tone, but there are a lot of these spikes and they increase in number as additional inputs are added, so there might be quite a lot of energy here all told. Anyone have any ideas? This thing should be linear under these conditions! Regards, Dan. Send instant messages to your online friends http://uk.messenger.yahoo.com
