soundfonts exporting very quiet #147
Comments
I agree… soundfonts should be the original sample loudness and db. |
What kind of file are you loading? sfz import followed by a sf2 export? |
I'll re-open this ticket if more details are provided |
I'm making sf2 files with .wav files i export out of audacity, and then it keeps coming out really quiet, sometimes restarting my pc and remaking it will work but it doesnt always work. @davy7125 |
Maybe something happened in newer releases of Polyphone? I found some old soundfonts playing at the original sample velocity, but when going to newer soundfonts, the db completely went down... I tried making loud soundfonts, and they became quiet. |
I don't know if this is linked but in the preferences, section "sound", there is an option to change the behavior of the parameter "velocity => cutoff filter". There is an explanation here: If this is possible I'd like to have a soundfont along with its exported soundfont, so that I can investigate. |
I played around with all the volume things or whatever is related, and then suddenly the original sample became quieter than the soundfont! I can’t for some reason send the soundfont, but I can share an MP4 on the differences between the sample and the soundfont later. |
Thank You so much for this great program. I have experienced this as well. Tried many SFZ exports and all end up with the same lower volume soundfont result, so it does not seem to be a specific code that only some SFZ instruments have that is causing this. I have read something along the line that SFZ has a different default attenuation (volume) than Soundfonts, so when you do the convert it appears to result in the Soundfonts default attenuation which is a lower value. The same thing unfortunately occurs when trying to export GrandOrgue instruments to Soundfont, you get the same lower volume soundfont result as well (also shifts the keyboard octave but I will mention this in a different post) Only available option in Polyphone that I know of is that you have to manually change the "attenuation" value before performing the export which is tedious if want to convert many items. Hopefully there is a solution for something like this, would imagine this is a pretty important issue as it hinders one of Polyphones two main functions (to create instruments and to convert them). Thank You again for creating such an amazing program. |
One more thing to mention that may help to figure this out. It is when you load them in other programs that you notice the difference. Anyways hopes this helps |
As mentioned in my other post, is this the official github page for Polyphone, seems strange that no responses have been made to any of my posts? Not even any new posts added by other users? Used a couple different sfz instruments to test out this theory. As mentioned above, all other programs that can load both sf2 and sfz seem to experiences this difference in volume, the only one that does not is Polyphone itself. Does anyone know if Polyphone has some kind of gain matching built in, that makes the output of both sf2 and sfz the same? Cause why would all other programs tested yield the same results? Most already know this but a quick note, Plogue Sforzando (a very popular product) cannot be used for this test because when it loads sf2 files it converts them to sfz format automatically. Has anyone else tried anything out or have anything to share? I made an issue post 176 which is a possible solution, if anyone is interested? |
closing this since it's dead and i don't use this anymore |
for some reason, when i export my soundfonts, they will be very quiet, and i cant find a way to fix them.
