When you buy a ringtone, there is poly and mono. Which one is the real song and which one is the beeps?

Polyphonic = multiple sounds. Much more realistic. Some older phones cannot support polyphonic tones.

A polyphonic ringtone is a ringtone that makes use of polyphony. Many mobile phones make use of such ringtones as they offer customers more options in customization.

The best type of ringer is a MP3 format.

A polyphonic ring tone is usually a MIDI recording. It specifies what instrument should play a note at a given time, while the sound is dependent upon the playback device.

This is in contrast to an MP3 ringtone, for example, which will play a digitally sampled recording.

Both poly and mono are beeps. Mono means one note at a time, while poly has lots of notes at a time, but they are still "synthesiser" versions. hHat you want is called "real".

My phone service calls the "real song," the one with voices and everything, the "super" ringtones. They cost more, and with sound quality of my phone, I stick with poly for better results.

Phones are SUPPOSED to ring when called.

I find not many things more annoying or distracting than a phone that plays a sample of a song when it rings.

Just a personal quirk of mine.

I don't buy ringtones - I use my own tunes. Good advertising...

Poly is like all together notes and Mono is one note at a time

It is a trick question. Polyphonic ringtones are different note that sound just like the song and Monophonic ringtones is just one note at a time. Real Tones is the real song that acutally sings the song. but if i had to pick between the two i would have to pick polyphonic.
