Newbie alert - question about MSU-1 sound volume

[double_helix]

Hi everyone,
                A new SD2SNES owner here! Well, having been reading about Krikzz's flashcards for years I finally ordered myself one .... I can't believe I didn't go for it ages ago. I'm impressed, and it's "unlocked" my SNES.

So, I've been playing around with it for a little while and I think I've got to grips with most aspects of the SD2SNES. However, I've noticed when playing MSU-1 enabled sound games that the volume of the music is quite high.  In some cases the music volume drowns out the game's sound effects. I've noticed in the menu that there's an "volume boost" to increase the volume. I'm wondering if there's a way to reduce the volume of the MSU-1 music so that the SNES generated sound effects can be heard more easily.

Thanks in advance for any advice given.

Doesn't really make sense though Further boosting should never result in quieter audio so I don't know what's been happening there.

Volume can get too high with Rev.H because hacks tended to be delivered with pre-boosted audio files specifically for the sd2snes instead of relying on the built-in volume boost feature. They can't be blamed really - some of them pre-date that feature.

With Rev.H finally fixing the volume without the need for volume boost, the pre-boosted audio files are inevitably too loud. I have decided against implementing a volume reduction feature to encourage hacks to deliver non-boosted audio. With Rev.H and v0.1.7c, MSU1 behaviour is now consistent between higan and sd2snes and no specific hacks should be necessary. For pre-Rev.H there is the volume boost feature in the menu.

qwertymodo is making a great effort to get all existing MSU1 hacks to distribute without pre-boosted audio.

Thank you so much for the replies ikari_01 & lee4. I'm sure that's not helped me, but a few others as well!

Is there any way for another person (such as myself) to lower the audio, using some kind of application? Because I'd really like to lower the volume of the Pilotwings MSU1 music.
My apologies for reviving a really old topic.

msu2wav will allow you to convert the PCMs back to WAV, then you can edit them. Then use wav2msu to convert the WAV files back to PCM.

If the tracks are looped at a certain point then the loops will be broken if you don't know the loop points when converting back to PCM. There's a way to find out the loop point value using a hex editor, but I'm not sure how.

It's at offset 0x4 and it's an unsigned integer. Just use any hex editor that displays hex values as decimal, such as frhed.

To me I found out turning the boost off did the best for the Rev of SD2SNES I had from Retrotowers after hearing Castlevania Dracula X you would have to agree. Making it more just made the music go way over the sound effects.

Boost option is only for RevE* and RevF. All above have hardware fixes for MSU audio. RevG the obsolete one and RevH or newer the recent good one. My modded RevE2 -> RevH for example has this setting completely ignored by me because of your mentioned loudness reason.

I kind of wonder if mine was a RevH though from the build quality of Retrotowers past efforts for me I just stuck with the Chinese SD2SNES for the sake it looked a lot more solid and haven't used the MSU1 feature for a few years now.
