After a very busy week, i've finally had some time to sit down and compare the Before and After recordings of the songs in my clone.
Here are my settings used for the recordings:
Equaliser mode: Natural
Volume: Maximum (level 31)
Connection: 2.5mm to 3.5mm adaptor, attached to Line out audio cable
First major difference i've heard would be the disappearance of Distortions. Some members have reported that they hear this soft buzzing sound when no music is playing, you might need to crank up the volume on your player to be able to hear that. Well, my player does that, and the Before clip recorded them down.
But the After clip, surprise.. The distortions are not there. Well, maybe they are present, but not audible at all. The 3 sample songs are located below, and all 3 exhibits the buzzing sound in the first few seconds. If you might ask, i started recording first before i clicked on the Play button.
Oh yes, you need earphones to be able to hear the distortions. You can't really hear them on speakers unless you are blasting the volume high enough.
Next difference i've noticed (and this was after repeated hearings of the music), would be the Faster response of the audio driver. Faster in a way i would describe it, that the sudden soft to loud transition was much better in the After, rather than the Before. The Before clip had this slight slur or draggy response, whilst the After clip had an instantaneous response.
I loaded both Before & After clips into an audio mixer to view the audio waveforms. And indeed the After clip did show cleaner step responses. Perhaps Clip 2 below would demonstrate this improvement. The other clip 1 & clip 3 are kinda "noisy" music..
Here are my Before and After recorded clips:
Clip 1 Before
Clip 2 Before
Clip 3 Before
