E-8305 unsupported file type error

Hi,

I DJ at home using a DDJ RX controller running Rekordbox (which I have always updated to the latest version fairly soon after release), but then export to USB and use CDJs when I play out. I never have any problems on my home set up but am getting the E-8305 unsupported file type error with increasing frequency when I play out. Two years ago it never happened, then it started to happen a little bit, then  during a gig  a few weeks ago (playing on CDJ Nexus 2000 mk1's)  it happened with about 1/3 of my tunes.

Now I know this error is supposed to relate to when you try to play tunes that are an unsupported file type, but that isn't actually what's going on here. I think that  because a) I bought them from Beatport/Juno download so they should be fine b) many of the files affected have worked in the past and most importantly c) during that gig I loaded tracks from my backup USB and many of the tracks that were showing this error on the first USB worked.

Looking at previous posts and stuff online I think it either to do with the USB sticks I have been using or is an error in Rekordbox.

I saw this post thread which makes me think it due to Rekordbox from version 4.3 onwards corrupting files as it exports

No that makes sense as the problem has been getting worse since version 4.3 was released.

But then I saw this interview with Avalon Emerson where she talks about CDJs not recognising USB sticks with slow read speeds

https://www.residentadvisor.net/features/3392

I use San Disk USB 2.0 sticks. Pretty cheap but I didn't think that would be a problem. The fact that the slightly one had more tracks with the error than the newer one is evidence for this being the issue.

Now the 2 possible ways to resolve this, downgrading to Rekordbox 4.2 or buying a £60 super fast SD card, both involve significant investment of time or money. So I would like to only do the one that is going to work. Does anyone in Pioneer know what is going on and can recommend a fix?

 

Thanks

Troubleshooting steps I'd suggest:

- Does it happen consistently with the same song? In other words, does that song throw the error every time it's loaded on the CDJ, or only sometimes? If every time, check that the song is indeed compatible with the CDJ. It could be as simple as the sample rate / bit depth. If it's only sometimes, try reformatting your SD card, give it a new (unique) name, export the tracks again, try once more. If it happens again, try removing the album art (especially for the Beatport songs).

- Try linking the players in EXPORT mode. If the song loads over the link, then the problem certainly isn't the song itself, but rather the medium on which it was stored.

Which version of rekordbox are you currently using? Which firmware is on the CDJs? That could be it as well.

Thanks for getting back to me.

It doesn't happen consistently with the same songs. There have been songs that show the error on one USB stick but then play fine when played from another one.

I have USB sticks rather than an SD card. Would you recommend playing from an SD card then? (As per what Avalon Emerson is saying in the interview I referenced above).

I will try removing the album art but would still like to explore all the things that could be causing the issue as I am playing out on 20 April and would like to go into the gig safe in the knowledge that this wont be a problem.

I am sorry I don't understand what you mean by linking the players in EXPORT mode. I know what EXPORT mode in rekordbox on my computer is but I have never come across it on CDJs and cant find anything online about it. Can you provide a link to info on that please.

I have always updated to the latest version of Rekordbox as its released, so am currently up to 5.3. I don't know about the CDJs firmware as they belong to the club, they are not mine.

What is your opinion on this thread, which seems to identify a fault within Rekordbox from version 4.3 onwards as the source of the issue

Hi, I solved the problem by formatting the usb sticks in the end. Thanks anyway

Glad it was something simple - if it pops up again, please let us know.

Hey guys,

I'm having the same issue coming up.
I've read these threads and gone through formatting multiple USBs,
Updating Rekordbox, re-analyzing tracks, checking the sample rate etc

It's happeniing with songs i've bought from producers on Bandcamp (some were of course free DLs too), so they should be trusted.

But this includes most tracks from an entire album downloaded come up with this error message, whilst a couple of songs still play.

This message has been a problem for me many times i've played and had sets lined up having to improvise and change set dynamics.

This issue has come up on NXS2000's, XDJ-1000's and CDJ900s.
I found that on the 900's, re selecting a track sometimes made it work.

Nonetheless, i have tracks that just insist on not playing regardless of their .WAV, 44100hz quality.

Sometime the error message comes up instantly, other times, the waveform quickly loads then become corrupt. I'm having trouble remembering if Error - Corrupt File has come up in the past, but right now, with using hired XDJ1000's and trying to work all the bugs, E-8305: Unsupported File is reading on close to majority of high quality downloads. 

Plz help.

Many Bandcamp WAVs have an issue where they are encoded with a non-PCM stereo flag; the players thus think they're a different encoding type and can't play them. The fix is either to convert the file or to use a hex-editor to make the appropriate changes.

From an email I sent to the Bandcamp support team:

Bytes 20-21 are the wFormatTag – PCM should be 1, another value would be for some form of compression:

FE FF > 65534

So this file is not a PCM, it’s Wave Format Extensible. This basically allows for a multi-channel WAV file to be created. This isn’t a standard WAV file format, and while should be backward compatible, is usually not used for standard 2-channel audio.

I changed bytes 20-21 (wFormatTag) to a value of 01 00 (a decimal value of 1; meaning PCM), and the CDJ was then able to read the file:

Man,

....what?

jesus.     

.. ...  ........         ...what?!

So i have to go through each song individually (which is at least 100 of them, and not even entirely obvious to figure out which ones without testing on the cdj and noting it down first).
And put them through this codex hack styled software and change the numbers that are in that red box from 20-21 to 01 00....? Which realistically changes it from a WavFE to a PCM.


How exactly do i do this, if you don't mind?
This is just not something i was prepared to be savvy with.
Is there seriously no other way, and how am i the only one to have come across this problem that it isn't a more known about common issue?

Do i click save or something after or like, how the fk does this work bro lol.
Do i download this hacking thing, or is it a right click into some advanced info?
It kinda looks straight forward, but this is alien to me man haha

TIA

The easier way is to dump them all into an app to convert them (heck, even iTunes can do this) and convert them from WAV to WAV, it will create a new output file which will work.

If you don't want to recode or convert it, then yes, the only option is to manually edit the file.

Bandcamp is aware of this issue and is working to resolve it, but for now, this is the fix on our end.

Hi, Im the original comment poster from a couple of years ago. I started getting the same problem again after formatting my USBs, and worked out it was due to bandcamp WAVs. Another solution is to redownload your bandcamp tracks as FLACs instead of WAVs. Still lossless but doesn't seem to have the same issue - I haven't had any issue with FLACs yet anyway

Ok, so i reformatted the tracks through iTunes.

It only worked with some of them.

Majority of those tracks still come up with unsupported after reformatting, deleting the old files and re analysing them through RB.

Again, some files (usually atleast 1) from the albums work. They seem to mostly be the files with less data. I.e ambient or reprise tracks, but not always the case.

What's strange is some files load the data and some tack longer to "think" before collapsing. Like they try to load but then just give up. I'd assume if it was the wrong format, they'd read it straight away?

So from now on, i'll make sure to download all files from Bandcamp as FLACs and will probably just go re-download the ones that didn't work. So just letting you know that simply reformatting them as WAV again isn't quite it.

Thanks for your help though!
