Ringtones Best Today Now Get
Set a ring tone for a caller or caller group.
On Nokia Series 60 phones, it is also possible to assign a different ring tone for each contact or each caller group. On Nokia Series 40 phones, you can specify up to five ring tones to five different caller groups, but you cannot specify ring tones for individual contacts. Those per-contact or per-caller group ring tones allow you to differentiate callers by the sound of the incoming call. Please refer to “Put a Face or Tune to the Caller” [Hack #27] for more on this subject.
Create Free Ring Tones
You can purchase and download ring tones for your phone from many web sites, including your wireless operator’s content portal site. Many leading musicians now sell ring tones for their new songs as both a revenue stream and an effective promotional vehicle. Part of the commercial success of the mobile phone ring tone business lies in the fact that, unlike MP3 music on PCs, ring tones are hard to bootleg and share. But advanced mobile phone hackers can create and use ring tones for free, from music they already own.
Use MIDI songs.
MIDI is the acronym for Musical Instrument Digital Interface. It is by far the most popular ring tone format. A MIDI file contains the musical notes of a song instead of the actual audio recording. Therefore, MIDI files can be very small, which makes them ideal for mobile phone ring tones.
WARNING MIDI songs are music only. MIDI cannot reproduce the human voice or other sounds that cannot be represented by musical notes.
The musical notes in a MIDI file are divided into several parallel channels. When a MIDI player plays the file, it simulates a different musical instrument for each channel and plays all the channels simultaneously. That produces the effect of a whole band playing the song together. Obviously, the more channels you have in a MIDI file, the better it sounds.
Many free MIDI files for popular songs are available on the Internet. However, most MIDI files you download cannot be used as ring tones because most free MIDI files have more than 256 channels. A Nokia mobile phone can play only 4–24 notes at a time due to hardware limitations. The Nokia Sound Converter program in the Nokia PC Suite [Hack #15] allows you to reduce the number of channels on any MIDI file and create Scalable Polyphony MIDI (SP-MIDI) files that are suitable for a selected Nokia device (see Figure 8-10). Using this tool, you can define channel priorities for the conversion, which specifies which channels to play and which channels to omit.
