SOS Magazine Test Files

[sarumbear]

The Sound on Sound (SOS) magazine has published a set of various audio test files. They are free to download.

The majority of test signals contained within the ZIP downloads are 24‑bit WAV files created using Adobe Audition, and for speed and convenience they are available to download separately.

It's nice they shared this but @pkane's Multitone Analyzer software is all you need!

And the SOS test files are missing white noise multitone

Can you point to the download page please as @pkane ’s about page doesn’t mention anything about it.

I’ve updated the post with a table of files. It shows white noise on it.

I'd seen that but that is white noise burst - not multitone?

It seems you are missing the point of these tones. They are used during production and for testing audio systems as a whole not for testing an individual equipment’s transfer functions like THD or IMD. Can you generate GLITS or even EBU idents let alone BLITS 5.1 idents with @pkane’s software? Does it do sweeps?

Same reason as above, you never need steady-state white noise when the monitoring is done by ear, I.e. during production.

Multitone has a function generator that supports a number of pre-built test signals and lets you construct new ones by combining their components. It does have sweeps, linear and log and can certainly be used to identify a channel with pink or white noise or any other signal, and of course, multitones. While it can output to any number of channels, it is designed to use a maximum of two at any given time.

Thanks. Strange that so many of their test tracks have very low levels.

Thanks. Strange that so many of their test tracks have very low levels.

That is because those are the levels that used during production. May I remind you that the reference level in production is -18/20dBFS. 0dBFS is never, ever used in audio production, hence it is exceedingly dangerous to use a test generator that can generate such high levels. The highest level in production is around -10dBFS.

As I said earlier, these are test files to be used on production not to test equipment. Every each one has a specific job that anyone who works in production will need but generally not available from laboratory test generators.
