Sample Conversion

[pmarchitect]

Hi,

Just tried converting a folder of samples from 32 bit stereo to 16 bit mono and when I put them in the Nerdseq they sound terrible, low quality and much longer.

Don’t know what I’m doing wrong? They’re wavs, I used switch converter for Mac.

Help?

I suggest you use another conversion tool. Also 16bit mono is not too common anyways. Try to go with normal 16bit, Stereo 44.1khz waves or make them 8bit mono or convert them to 8 bit unsigned raw directly. And the chances are there that your tool adds additional information in the wave file itself which the nerdseq probably can't handle, then it maybe doesn't matter how your set it. Then you definitely got to switch to another tool.

I tried 16bit stereo 44.1 wav first but same issue. There is another thread I found on here with a few people with the same issue saying that I ly 8 bit works, but that the manual says 16 bit works to. 

Can you confirm that 16bit is possible? Thanks.

I’ve tried 8 bit and nothing works.

Same issues.

Anyone???

Hello all,
I too started to experiment with samples today. I had the same issue but I manged it to work.
I'm using Audacity latest version. I think it is a problem with header as Thomas already mentioned in some other topic.

Make sure you select
format: Other uncopressed files
header: Wav(Microsoft)
encoding: Signed 16-bit PCM

For me it's working very well.

I just tried these exact settings with Audacity and while it is better, there is still some digital noises at the end of every sample. 

Do your samples play totally cleanly?

Both 16 bit and 8 bit mono unsigned raw work for me. I make the sample into 8 Bit mono, inside Renoise (can do this in audacity), bounce the sample to Audacity and save as an 8 Bit mono unsigned raw file - making sure to erase any meta data attached to the file before the save.

If I have memory issues, I send the sample up 1 or 2 octaves and rerender it, then lower the pitch in Nerdseq back to original. Artefacts are found doing this but I kind of like them.

http://aminet.net <--- You could also go here and salvage some ready made 8 bit samples. They'll mostly be in .IFF format but Audacity can convert them to 8 bit unsigned raw.

A nerdseq sample block / sample forum would be cool, so we can share our Nerdseq samples w/ the community.

Yeah I had to convert all my samples to 8 bit mono unsigned raw before everything worked as expected. I had signed raw for a while, and it still distorts like crazy.

"unsigned raw" sounds cooler too

I can confirm that all sample types mentioned in the manual: wave 8/16 bit mono or stereo and 8bit raw unsigned work...
But some softwares use wavefiles with loads of metadata and extra information which the NerdSEQ can’t simply decode. Mostly because it has an easy wave file decoder and assumes the standard simple implementation that you can find everywhere but not specials that are added.
Implementing a full stack would be probably as big as the NerdSEQ code itself, if not bigger.

They are many tools out there to either convert or write your wavefiles in all kinds (except 24/32 bit) which work perfectly with the NerdSEQ. Also some batch conversion tools are available and have been posted here.

I just ran through all samples. I can say that 95% of them are OK. I imported a lot of noises and glitches. Most of them are only fraction of second long so I really can't tell if they are ok. But from 22 kick samples only one sounded bad.
