I vaguely recall that Vorbis requires a fair bit more processing to decompress, enough to be a potential issue 15 years ago, but on modern computers it's barely detectable and doesn't effect performance at all.
- bsder 10y agoThe problem now is battery. MP3 almost always has hardware decode which is really power efficient. This isn't as bad nowadays since audio decode isn't that intensive relative to keeping your WiFi on.
- out_of_protocol 10y agoopus can be decoded by hardware as well, (seek by name VP9 or webm) - most modern arm chipsets do so
- derefr 10y ago...such as those used in the majority of Android/iOS devices? That'd be the important bit.
- dsr_ 10y agoWifi might be 100-200 milliwatts, but a laptop's speakers are likely to be 500-3000 milliwatts. Headphones are likely to be about the same as the wifi, but can vary wildly.
- derefr 10y agoBluetooth speakers/headphones change that dynamic slightly; the amp+required battery ends up on the receiving end, so you just have to figure what the Bluetooth stream itself costs.
- khedoros1 10y agoMy recollection matches yours. I remember loading a custom firmware on my iPod, around 2005. Vorbis support was a big new feature; they'd just figured out how to get decode working fast enough on its 80MHz ARM7 CPU.
- jorvi 10y agoProbably Rockbox? iPods their clickwheel interface and it's software was amazing for the time, but other MP3 players generally had kinda icky interfaces. Rockbox fixed that :)
- khedoros1 10y agoYes, it was Rockbox. I followed it when they were first bringing it up on the 4th Gen iPod.
- TD-Linux 10y agoThe "fast enough Vorbis" was likely the addition of Tremor, the first fixed-point Vorbis implementation. There's a nice (but with many old entries) chart of decode speeds here: https://www.rockbox.org/wiki/CodecPerformanceComparison https://www.rockbox.org/wiki/CodecPerformanceComparison On newer hardware + software, like the Clip Zip, the gap is much smaller and the performance way higher than needed in any case (except for HE-AAC, the clear loser).
- ams6110 10y agoI concur based on experience. I have a cheap music player that will play Ogg-Vorbis files but it skips and stutters. mp3 files play flawlessly.
