Dropbox and glitches

[Omega Arts]

No. Working fine here.

Never had that problem with Dropbox. But I tend to compress files in zip when uploading, maybe this avoids the glitch?

[allstar]

I've not had this with Dropbox, but got it with a file sent via sendspace once.

Best practise is to never transfer audio files around the interwebs unless compressed as zip or rar. When transferring masters, make sure you also use md5 checksums.

Raw wav files have no method of verifying - no checksums, no CRC. With zip/rar you at least get CRC.

I usually use wetransfer and never had any problems with that. I must say that if you just add the wav files (more then 1 file) to wetransfer it makes a zip out of it which is indeed more secure. But even though it is only one file, no problems at all and i use it a LOT. But still.. i find it really strange that dropbox adds these glitches and still it nulls except for the glitch itself. I can't imagine i'm the only one.

always zip your files, not for the compression, but just for the checksum part. files can appear to be identical in size and even in waveform but if they don't have identical checksums, they're not the same file.

I used to zip all my files before sending it out but let's say, the last 2 years i don't because i never had any problems untill i started using dropbox as well.. time for zipping again indeed.
But still wondering if anyone else has the same problem because this could ALSO happen to a zipped file even though it doesn't (at least i hope..) pass the checksum.

[pmx]

if it happens to a zipped file, it won't unzip. at least in theory, but i'm a firm believer

In theory yes.. But that is what i'm afraid off.

I have had lots of problems receiving zip and .rar files.

I have a dedicated ftp server. Each client has with his own password/username and mix/mastered folders.

Very simple to set-up, cheap and trustable.


In 5 years, I think only twice I received glitched files .
The problem was the "turtle speed" conexion of these specific clients.

[dynamike]

I have used Dropbox almost exclusively for the past few years. I have a 100G account.

I send raw waves all the time with no issues. The only issue I've ever had is telling a client I sent a download link before it was fully uploaded. That was obviously my bad, not Dropbox.

Guess I should start zipping everything thought. That makes sense. Never thought of it that way before.

[SASMastering]

No glitches that I recall, but very slow up/down site in my experience and somewhat over complex to operate for a basic file up/file down site. I avoid it as much as possible myself.

[Bishbashbosh]

Yep, I've had some Dropbox weirdness in the last week or so.... Files which look ok are in fact blank.... It's been fine for the last year and I've been using it very heavily for both a TV show and film score.... Suddenly it's been more than a bit flakey...

No DropBox problems here, I love that it's multi-platform. Last week a client sent me a raw .wav from another file delivery service (can't remember which one it was, but it was one of those that tries to trick you into downloading other crap and not the actual file you need) and it had a couple seconds of missing audio in the middle of the file. Asked the client to .zip up the track and re-send for reasons already explained above.

Just wondering what OS and version of the dropbox tool you are running.

Currently in Mountain Lion with (I'm assuming) the latest version of Dropbox. I've been using it since Leopard with no problems.

[Bishbashbosh]

On Lion 10.7.4 (which I have been for a while)

No changes at all here (am mid TV series so no upgrading for me for a while..!)

Issues the other end have been on 10.7 and 10.5 as well as Win7.

I'm guessing a Dropbox server issue perhaps?

[JTransition]

I've been using Dropbox for a couple of years(pro account),
We tried it as a last resort before going for a FTP server but it's been rock solid (glitch free)Quick and simple,I am impatient when it comes to clinking links and waiting for stuff to download but with Dropbox the customer puts the file into the shared folder and it appears on the Internet computers desktop.
We transfer is also quite good in my experienceand .
I think zipping all files is a must .

[Babaluma]

yeah, if you zip/rar/flac first you should be fine, think all will give you a checksum error if something is amiss.

[aTelecine-Lex]

To those that have had issues w/ DropBox and "glitches" have they mostly been occurring recently?

I have just had a few audio files with varying errors during the past 2 weeks or so - But, never before that I can recall.

I am just curious if it's a DropBox bug that they can be made aware of - Or are working on.

That said, it's always good practice to "Zip" a file(s) when sending over the Internet - DropBox hadn't given me an issue for so long I got bit lazy.

Back to Zipping for now

Best,

Yes, this happened to me passing master mixes over to the band. No idea how it could happen, but it did.

[huejahfink]

I've always zipped or rarred but not so long ago when sending off some pre-master wavs to a respected cutting engineer, he told me he wanted me to resend them with no file compression because he said zipping negatively effects the sound quality, despite the fact that you can prove they are mathematically identical with a null test "but my ears tell me I am right."

Can't please everybody!!

No - You really never can...

I am all for people "hearing" things differently and having differing opinions with regard to quality.

But when people refute proven science regarding quality, or exactness, via a total null cancel w/ conviction - I have to reconsider my opinion of the quality of their "hearing".

Often I wonder if these people realize how differing in the face of science makes most people think they are not only foolish, but if they work in pro-audio - A potential liability.

Alexa

Well I don't know that I took it THAT way Alexa.
I respectfully disagreed but just sent back the audio as unzipped for him.

I'm not calling out names but I have a lot of respect for this engineer, they do awesome work. If we don't agree on this point, that's fine and I respect their opinion even if I don't follow that idea myself. If it makes a difference to them - then so be it.
This person is certainly not alone in their general distrust for the digital world. There are people out there that think simply copying a file (whether from drive to drive or across the net) is bad for the audio.

It kind of reminded me of the idea that a photograph could steal a portion of the subjects soul! In this particular case (or cases) it seems that there are folk who see the mathematics to be only one part of a much bigger picture.

Sorry after reading it back my post reads a lot harsher then it was meant.

Regardless, I would also make an exception if actually knew the person in question - I was more thinking about those whom shout such things continouly from their digital soap-boxes in too many threads on GS.

Cheers,

This is also why dual-mono files have better stereo separation than interleaved.

You can easily hear the bits from the left channel rubbing up on the ones from the right.

As far as file corruption from transfers, I can't say I've had a single case ever. There have been times where I've heard a click that I've asked the client about, but it has always turned out to be in the original file.

But always Zipping or Raring is so easy there is no reason not to do it every time.

Just don't tell the crosstalk plugin developer.

Unless polarity inversion has taken place, in which case they rub down on the ones from the left. Right?

You have made much progress in your journey Grasshopper.

DC, if I use stereo fx and export dual mono, I run into troubles, no?
