Wav files in my Samples Folder are "unsupported"

ooijj

Hi there,

I have copied a bunch of .wav files into my Samples folder but when I attempt to load any into either a new Synth or Kit, the display shows "unsupported" and the files do not preview or load.

Other .wav samples in the folder are audible with preview and can load.

I've checked/played the unsupported files on my laptop and they are not corrupted - I can play them. So is there something I'm missing? Are there limitations to the sample rate or bit depth?

So after uncovering this discussion I resampled the files from 48khz to 44.1khz and they are loading/previewing now.

if u attach the unsupported files as a zip, i am interested to have a look. generally 48khz should not be a problem, i suspect there is something odd with your wavs and the Deluge has not all the error tolerance of common desktop audio players. so far i found 2 oddities with corrupt meta data (mp3, bits) the Deluge does not handle https://github.com/amiga909/deluge-synthstrom-utils/blob/master/samplefixer.sh

Hey @amiga909 , thanks for the reply. Here are the files

Since converting them I can preview and use the files on the Deluge, but they seem to be giving it some trouble when I use them in songs. I was working on a song that started freezing at a particular point and totally jammed the machine. I had to power off, and when I reloaded the song and played it again, it froze again. So maybe my conversion method wasn't so robust? I also think the Deluge isn't good at handling and processing long audio files. I often use long atmos files in my work, and have found that applying too many effects (reversing, modulating, filtering) on the Deluge can overload it.

Does the script you link to above clean up metadata. Do I just run it in the folder where the sound files are?

Thanks. I tried to MULTI load the folder in a kit preset. I can confirm it aborts with UNSUPPORTED, I removed the .jpg file but still did not work.
I had a look if some meta data look odd:
`File: Hainbach - Isolation Loops (soundpack)/Hainbach - Isolation Loops (soundpack) - 22 Ciat-Lonbarde Cuts.wav
File type ID: WAVE

Num Tracks: 1

Data format: 2 ch, 48000 Hz, 'lpcm' (0x0000000C) 24-bit little-endian signed integer
Channel layout: Stereo (L R)
estimated duration: 15.333042 sec
audio bytes: 4415916
audio packets: 735986
bit rate: 2304000 bits per second
packet size upper bound: 6
maximum packet size: 6
audio data file offset: 80
optimized
source bit depth: I24`

At first glance it should not be a problem. I will keep an eye on it.

You need a Mac and some experience with the terminal. Linux should work too.

• Make a backup of the SD card
• Get the script from https://github.com/amiga909/deluge-synthstrom-utils/blob/master/samplefixer.sh, I have just fixed something, please get the newest version and check the docs
• There are 2 commands clean and convert: clean command gets rid of all non audio files, including files that appear to be a WAV. convert command resaves files with fishy meta data and files with low bit/sample rates to 16bit/44khz.

Looks like it's Mac only. On Ubuntu 16.04 I get Error: afinfo is not installed.
Some googling reveals that afinfo is a mac-only library.
Will give it a try on a macbook later...
