Please help about LMMS crispy noices

[musiczero]

Is there any explanation why compare to any others audio work stations( for example- Studio One Free) in LMMS most of the sf banks ( the built-in banks and the added ones too) always making such a crispy noises and sounds in a tracks, the work with LMMS always bothering me with that, I am forced to always remove all that noise. Is there any option to solve the problem? and will you work on it in a future? It is not the problem of my PC or any drivers, there is no problem with them, and all my friends having the same problem with crispy noises.

by 'sf-banks' you refere to the sound-clips-samples in the MySamples section? right?
My gues is that you have clipping.
Try to enanble the visualisation.
Do you see yellow or even red curves?
If so add a limiter to the FX-tab, and make ajustment so the clipping disapear.
Otherwise, extensive resonance ao loudness will also result in clipping, so alterations on those settings can aid you too.
Was that it?

Thank you for replay. I already try before the FX- tab adjustments, to make the red yellow clipping disappear, it helps, but it makes the sound too low and quiet. The problem is that i am making music for radio, and i need it almost studio quality, i guess that even if i fix the FXtab clipping, it will be to quiet for studio-level quality, or anyway on a professional good music radio equipment all the clipping in my music will appear( all clipping i may not hear on my PC and speakers or headphone, when i make the volume lower, or the FX-tab adjustments.) Sometimes even the FX tabs adjustment or volume adjustment to low does not help in some banks.

I have the same problem with some of the sounds. Try using an equalizer to find and lower the volume of the frequencies that are too loud. Hopefully it will not make the instrument really quiet, or sound too different. I would check the lowest frequencies first, because for me that is usually were the problem is.

hope that helps

Oh i will try that, can yo please upload some video tutorial on youtube how to change the frequencies?It could help many people i think. If i understand right i should connect each track to different channel of FXtab, and than change the volume in each channel? Or it is not the right guess? Sorry. I just don't know how exactly to change frequencies in equalizer and where to find it.

[musikbear]

don't know how exactly to change frequencies in equalizer

nah changing freq is not posible. what you do is to seperate instrument frequencies so the different instruments has mostly own freq-span.
I will post something on this later
In respect to how to use the mixer, you can whatch my tut on Downmixing a song on youTube -or one of the gazillion other on the same subject :p

Thank you musikbear, that was what i was guessing. And great YouTube tutorials, you are explaining everything slow and easy. Like your "ratsOnSpeed" music.

Don't forget your export settings. The main two to mess with are sample rate and bit rate. Sometimes for good quality, you have to dial those two up. (Personally I don't think a bit rate less than 160kbps is going to sound good. Sample rate seems less big a deal. And iirc, CD tracks usually are 192kbps @ 48000Hz.) Too much compression via low settings can muddy up the sound, particularly if there's musical complexity occuring in both high and low frequencies at the same time. (Excessive compression with values set too low can be like unintentionally running a cutoff filter, or if really bad, it can make the "underwater" sound a sweep filter can make.) Dialing the values upwards makes for bigger files, but that kind of resolution may be useful, particularly if you're remixing and applying effects to a track made in LMMS in some other software. Compression noise also seems to stack up if compressing again for an .mp3 file from other software. The less compression there is, it's less likely there will be quantization artifacts, and periods of clipping (if not overwhelming) become much shorter. Basically when messing with those values, you're trading off ability to use dynamic (and perhaps frequency) range for a smaller file size.

Perhaps a better (more technical) explanation can be found at these links?

Interesting Topic. Hmmm.........

This tips do not apply if you hear the crispy noises in your exported songs, I think...

If the buffer size and latency is set to too little, you might experience cracks in your sounds.
