	HE-AACv1 (AAC+)		X
	HE-AACv2 (enhanced AAC+)		X
	AMR-NB	X	X	4.75 to 12.2 kbps sampled @ 8kHz	3GPP (.3gp)

	MP3		X	Mono/Stereo 8-320Kbps constant (CBR) or variable bit-rate (VBR)	MP3 (.mp3)
	MIDI		X	MIDI Type 0 and 1. DLS Version 1 and 2. XMF and Mobile XMF. Support for ringtone formats RTTTL/RTX, OTA, and iMelody	Type 0 and 1 (.mid, .xmf, .mxmf). Also RTTTL/RTX (.rtttl, .rtx), OTA (.ota), and iMelody (.imy)
