Media applications52The required quality level may depend on your demands,the headsets used, and the surrounding noise. For MP3s abitrate between 128 and 192 Kbps usually gives resultsgood enough for listening to pop music with your device.WMA or AAC generally gives a similar result as MP3 withone step lower bit rate (96–160 Kbps). Variations of AAC,such as AAC+ and enhanced AAC+ (eAAC+) provide CDquality audio at bitrates as low as 48 Kbps. Classical musicand music with nuances usually require a higher bit ratethan basic pop music.For speech or other sources where the quality of the soundis less important than saving storage space, you can usebit rates between 8 and 64 Kbps. At low bit rates WMA orAAC generally gives better results than MP3.Variable bitrateYour device also supports variable bit rate (VBR). VBRmeans that the bit rate of the encoding varies with thecomplexity of the encoded material. When using VBR, theencoding is optimized to preserve a constant audio qualitythroughout the track rather than losing quality forcomplex music sections as with constant bit rate (CBR)encoding.Visual RadioPress , and select Applications > Radio. You can usethe application as a traditional FM radio with automatictuning and saved stations, or with parallel visualinformation related to the radio program on the display, ifyou tune to stations that offer Visual Radio service. TheVisual Radio service uses packet data (network service).You can listen to the FM radio while using otherapplications.If you do not have access to the Visual Radio service, thenetwork service providers and radio stations in your areamay not support Visual Radio.You can normally make a call or answer an incoming callwhile listening to the radio. The radio is muted when thereis an active call.The radio selects the used frequency band based on thecountry information received from the network. If thisinformation is not available, you may be asked to select theregion you are located in, or you can select the region inthe Visual Radio settings. See ‘Settings’, p. 54.Listen to the radioNote that the quality of the radio broadcast depends onthe coverage of the radio station in that particular area.
