How can I know which devices can play WAV files?
For example, this phone does support MMAPI:

Does it mean that BY SURE it can play WAV files?

Hi,

I've done some searching and haven't found any system property that would show exactly what the phone can play though it's safe to assume that if the phone supports recording sound in a certain format it can also play that format. So use System.getProperty("audio.encodings") to see what formats are supported. If "encoding=audio/wav" or "encoding=audio/x-wav" are among them then you're in luck :).

Also, this document shows a list of the media formats supported by various Nokia phones. And if you're developing the application for a specific device always check the supported media formats for it: http://www.forum.nokia.com/devices/matrix_all_1.html

thanks, but I need to know this info in advance, to decide which phone to buy!
I'll take a look to your links.

There's a difference between what audio formats/codecs the phone "natively" supports, and which are available from/for a Java MIDlet. I don't know if that's documented anywhere properly.

In other words, a device can play WAV files just fine using native/built-in applications (like as ringtones or its music player), but they might not work for user-installable Java applications.

I found out that 6021 does NOT support natively WAV files.
So, new questions:
- is it possible to add WAV support to j2me? (3rd party library)
- is it possible to use MIDI to produce sounds a few ms long and at 18000 Hz frequency? (sound synthesis)
