Wow, this was a long journey. I procastrinated this record for months. The selection was already done but I was struggling a record signal so I gave it up. I choose Serato Intro for this mix altough I have a Serato DJ but it has a big mistake: it has only a decimal pitch range which is not enoug for a good beatmixing.
Here are the tools: Sound Forge 7.0 for the recording (additional hardware: Terratec USB 5.1 Mk II via analog output), Serato Intro for the mixing (mixer: Denon MC6000 Mk II). Effects: Flanger, HPF, LPF, Reverb
I notice some jittering in the vaweform AFTER recording & encoding (LAME codec). I don't know what cause this proble because I recorded this mix to a non-system SSD and I switched off all of integrated sound cards and energy managements. Perhaps next time...
