I was wondering why AJ requires authors to submit tracks in 44.1 kHz, whereas almost every buyer will end up converting them to the industry standard of 48 kHz. Sample rate conversion is tricky, especially for conversions like 44.1 to 48 where the target is not an exact multiple of the source. Sound quality may be affected. A lower sample rate certainly saves storage space but the size difference between a 44.1 kHz wav file and a 48 kHz wav file is only around 10 %.
Any ideas?
Definitely wish the file type restrictions were a little bit more relaxed. Should be able to have mono or stereo sound effects. It would also be great if we could have up to 96kHz/24bit as these add even more utility for sound editors.
Good question!
I think similar questions were carefully considered and adopted the “Golden mean”.
I know TV shows etc. have 48 kHz audio but I think few buyers will convert (or even know about it) since most of it is going on YouTube/other web use.
I think AJ USED to accept both but then stopped. Evidently, there hasn’t been any major requests from buyers to reinstate the option after hundreds of thousands of sales.
I’ve never had, seen, or heard a request for 48 kHz after many years and thousands of sales. Have you had requests for it?
I guess, if they do need to convert, upsampling is not a problem.
48 kHz/24 bit is the audio standard for DVD and broadcast, and while it is true that most sales here go to Youtube and other web platforms, selling a broadcast license is something to celebrate, from what I see in this forum. So we have a great incentive to comply with their standards.
As for Youtube, they recommend a sampling rate of 48 kHz for audio (YouTube recommended upload encoding settings - YouTube Help) Being Youtube, they don’t make this mandatory, but it is likely that everything else is converted to 48 kHz during upload.
No, never. That’s because video editors or producers don’t know about this unless they have a special interest in the audio side of things. And they are not supposed to, because that’s our job. I don’t know about the emission standards for cars, but when I buy one I assume that it is compliant.
Video editing suites support a wide variety of formats and codecs these days, so when they add audio assets into their projects they might not even realize that those assets are being converted in the background. But ask them to go to their render settings and tell you how they render audio, there’s a 99 % chance that they’ll say 48 kHz/24 bit.
If a competitor offers tracks at that specification, it will be rendered as is, without any degeneration. But a 44.1 kHz-16 bit file provided by AJ will be upsampled and padded quite a bit. That might affect sound quality.
Just a point to consider in this highly competitive world of ours
