Boo-freaking-hoo. Cry me a river, poor streaming services without the technical know-how to calculate an ad’s volume. We can’t expect them to know how audio works!
> Additionally, as the opposing groups previously pointed out, streaming services must contend with a broad range of output devices, including TVs, tablets, and phones.
See, that’s just flat-out lying. What’s this mythical circumstance where playing audio A at the same volume as audio B on one device will magically make A louder than Bon another? Especially when dealing with server-side ad insertion, as the article discusses, where the service has full control of the input files and the output stream? This reads like a restaurant trade group claiming that it’s impossible to know how much salt they put in the gravy.
Regarding your second point: as any audio engineer or electronic musician knows, the same exact audio absolutely will sound very different on different speakers, depending on how well they replicate various sounds, what level of gain is being applied, and the volume (which is different from gain, although people confuse the two).
That's even before you get into the fact that many modern devices, like smartphones, will apply their own compression or sound processing before playing the sound, sometimes to compensate for those deficiencies and make them less noticeable, and sometimes to "enhance" the sound.
Loudness/volume (technically different things but let's conflate them here) are also unintuitive because human ears don't have a flat frequency response curve, and some things will be perceived as louder despite being the same volume, or vice versa.
Advertisers actually can (and do) take advantage of this, by using sound engineering to make things feel louder while staying within the desired volume, by targeting the way humans perceive the sound.
This isn't a defense of the advertising/streaming companies here, because it is a solvable problem. But it is true that this is a problem that they need to solve.
Regarding the perceptual volume differences: while true, that’s also a solvable problem. Output volumes can be calculated using standard curves. In any case, TV broadcasters have had to figure all this out years ago.
Start at 1/4 the volume they use now.
After all, they don't need to approach compliance tuning and debugging from the loud side. They can start at a whisper and work up.
(I hope they get fined into bankruptcy, if they try to claim they're "working on it", but do so from the loud side.)
