    It has nothing to do with how the sample itself was made, songs can set any sample into this mode, that's what SNES is capable of.


    Ah, OK, I had no idea! That's kinda cool!

    My take-away from the exercise was just that I need a set of speakers that's actually stereo, and based on what you've said that's probably the only real solution (or make an audio cable that only sends 1 channel to the speaker, but that would have its own drawbacks).

    Thanks for taking the time to reply! :)

    I was playing Ninji Story by lush_50, and this track is used in the level "Face First". It's one of my favourire Jazz tracks, and this is an amazing port, well done.

    However!

    I sometimes use a bluetooth speaker with my PVM monitor, which has no speakers of its own, and I noticed that the bassline was completely absent when listening on one of these devices.

    I spent hours checking my cabling, connections, and running tests with both Nintendo's test cart, and the 240p Test Suite, thinking maybe I was only getting one audio channel, but to no avail.

    Turns out that (1) the bass sample in this song plays on both channels anyway, and (2) when it does, the left and right channels are 180 degrees out of phase, so when the channels are merged to play on a mono speaker, the bass vanishes without a trace! I was able to reproduce the effect in Audacity, too.

    Someone more knowledgeable on SNES music, what would cause this? Are there two copies of the bass sample that are 180deg out of phase with each other, or is the SNES doing something funky at playback time? If it was the latter, wouldn't all the audio cancel out?

    Edit: Audacity screenshot:



    Top is the recording from the line-in, bottom is the the stereo track's two channels mixed to a mono track. The bass, and only the bass, has gone missing!

    Alright, I didn't know I could do that with the labels before. Will sure put that in mind.

    very nice job with this one! I found you were using label loops the wrong way sometimes though:

    1. (1) (1) (2)
    2. (3) (3) (3) (3) (3) (3) (3) (3)
    3. (3) (3) (3) (3) (4) (4) (4) (4) (3)

    this is not how label loops should be used, as label loops can also be repeated by placing a number after them much like regular loops:

    1. (1)2 (2)
    2. (3)8
    3. (3)4 (4)4 (3)

    i did fix them myself because they weren't enough for me to write a removal log, but please keep this in mind in the future. i also lowered the global volume just a bit.
