Sound Quality Dsi-XL vs DS-Lite The Pepsi Challenge

Post by ghostils » Mon Nov 19, 2012 9:42 am

DSi-XL vs DS-Lite sound test

WARNING THIS IS FREAKING LOUD!

http://soundcloud.com/bponas/dsixl-vs-dslite-snr-test

Same song on same cart
Pattern 1 default INIT, max vol, max channel vol on all channels C4 Legato 16 steps syn1
Release set to max, everything else default.

Pattern 2 default INIT, no sequence data, max channel vol, max inst vol
Pattern 5 default INIT, max vol, max channel vol on all channels, C4 Legato 16 steps syn2 fx delay, default settings but 100% wet.


Recorded on a behringer 1202FX, +4 DB stereo input, 12 oclock, unity gain on master, into Tascam US-800 inputs 3-4 12 oclock. Not normalized using Audacity 32bit 44.1 each channel comes in mono since it multi-channel records.

Silence 3 seconds at rec vol both consoles on boot screen silience, 3 seconds normalized on each.

What we get is the DSI has less volume in the more audible bands, and more volume in the 7-15K bands, while the DS-Lite has much more volume in the 80-200hz realm, hence it sounds dirty and has a hum.


Playback in order. DSi-XL, Synth1, Silence, Synth2 Delay, Silence for 4 patterns, DS-Lite Synth1, Silence, Synth2 Delay, Silence for 4 patterns at 120bpm on both to let the buffer fade out. Silence until normalized DSi-XL NO Sound Boot Screen, DS-Lite Silence, DS-Lite Normalized no sound.

Quite a bit different when you hear the last part. A little noticable on the tail of the DS-lite delay, less so on the normal note. DS-Lite is a tad quieter to record as well.

Re: Sound Quality Dsi-XL vs DS-Lite The Pepsi Challenge

Apologies for the wall O text, but it saves me from PM'ing a bunch of text files for the graphoholics =D

The dumps are from recorded "silence" at the boot screen long after the initial startup jingle, at the same settings as everything else so its pure dac noise well as pure as I'm able to get with my setup anyhow.
