Project Description

Required: A karaoke/singing iPhone app that grades a user’s singing ability similar to the Sony PlayStation Singstar game. This is coupled with a web-based admin application to create downloadable songs for the user app.

Administrator Application:

This is a web-based utility that allows administrator to create songs for the iPhone application:

1. Administrator uploads audio file of song (MP3/M4A)

2. Utility analyses singing from song and sets scoring coordinates the iPhone user will be ranked against. Scoring coordinates based on:

a) Rhythm: time/interval

b) Pitch

c) Relative loudness – measured against other lyrics in the song’s loudness

d) Timbre

When measuring singing, instrumental sound should not be measured where possible. Some instrumental disturbance may need manual clarification from administrator

3. Administrator adds text lyrics, with timing synchronized to the song’s lyrics (this will be assisted with a graphical equalizer display similar to a standard audio recorder)

4. Music file saved with scoring coordinates and text lyrics, compressed in format readable by iPhone app below

5. Administrator also defines scoring rules based on coordinates above

User Application:

This is an iPhone application that allows a user to sing along with a song, measuring the user’s singing ability against this song:

1. User selects song (stored on device/downloaded from server)

2. Song lyrics displayed in karaoke-type interface with words highlighted as they are played. User also hears song through headphones and sings along into microphone

3. User has option of recording singing through iPhone camera

4. User’s singing compared to scoring coordinates with result displayed in real time during song

5. User details, song history, user video & song recording files, scores and GPS location uploaded to MSQL database. There is also interface with social media APIs

To be considered for this project you must:

1. Have experience working with sound manipulation for an iPhone app

2. Send links to 1-2 projects that you believe are relevant to this application

3. Template messages that are obviously cut & pasted will be disregarded
