What determines the excellent bass/treble settings of the HTML5 player that Firefox uses?

Veröffentlicht

MP4 music files always have a great balance of bass & treble when I play them in Firefox. Much better balance than if I play them in a media player like VLC Media Player or KMPlayer. In fact, it's so much better that I've made Firefox my default MP4 player, despite the inconveniences that come with doing so.

This has been the case for years now and I'd really like to understand what is going on here technically; what exactly it is about the HTML5 player in Firefox that is allowing it to have such great sound.

Hi JuzBeKind, on Windows, Firefox uses Media Foundation to decode MPEG-encoded media. If you compare Windows Media Player, is it similar to Firefox or is there more going on than that?

Also, I should mention that support has ended for Firefox 48. These are the current releases:

Presumably you are using an old version because of certain features or add-ons. Let us know if we can help you find replacements so you can use a more secure browser.

It appears Media Foundation isn't present in XP, and this Firefox audio phenomenon is present in both XP and Win7. Still, that's a valuable piece of info, and the first relevant piece of info I've ever received regarding this Firefox audio phenomenon. It seems there are very few people in existence who understand Firefox's internal workings (or they all hang out in some other area of the Internet somewhere).

In Windows 7, if you compare Windows Media Player, is it similar to Firefox or is there more going on than that?

In Win7, it does indeed appear to be the same, or very close to the same. Good test suggestion.

Also, I should mention that support has ended for Firefox 48. These are the current releases:

Sorry, I forgot that this site automatically tries to collect version info. I'm not actually using Firefox 48, that's just what my user agent spoofer is reporting. I'm actually using Firefox 66 in Win7 and Lubuntu. I am still using 52.9esr in XP though.

The ability to use the hundreds of older add-ons is just a bonus. The primary reason I'm using the older version is that it's the last version for XP, and XP is too good of an OS to give up entirely any time soon.
