MP3 compatability

[paobrasil]

Good question, I want to know this too.....I use soundbooth to save my wav files....

Andos - so what's a good quality level for WAv files?

Sorry but I can only tell you to experiment a bit Acceptable sound quality can vary from sound to sound.
I think that low-volume sounds can be compressed more without being noticeable though but I'm not sure.

Does this performance increase with quality drop count for MP3s too?

[Anders]

The MP3 file will be directly decoded by the internal iOS hardware decoder. I doubt that playing MP3 will have any performance penalty at all.
iPhones and iPod Touches are pretty much designed to be able to play music with the least amount of processing possible to save battery.

The hardware decoder is only used for the first MP3 played. If you play other MP3s at the same time, they will be decoded by software, thus impacting performances.

Francois - so is it better (performance-wise) to stop an MP3 playing on a particular channel before playing another one on the same channel, or does it not matter and only a problem if playing another MP3 on a different channel?

[Francois]

The previous sound playing on the channel is stopped if you play another sound on the same channel.
You should only stop it if on a different channel.

François, taking advantage of the issue, does not work the condition: "has left playing XXX audio in a specific channel", or iOS or Android, have already reported it in the other forum, take this opportunity to report it here.

[Francois]

Heee sorry José, I do not really understand what you say. Are you saying that the condition does not work?

[Koji_Kabuto]

Don't worry François, with my poor English, sometimes even I I understand, lol.

Does not work, the condition when you want to test a sound on a specific channel is no longer sound. For example, if the laser1 sound stopped sounding then I do an action.

Does not work if it is direct, it has been sounding "laser1" then get the following...
