RTTATuner for iPhone

Real-time intonation analysis on iPhone

RTTATuner implements Real Time Tuning Analysis (RTTA), a novel approach to measuring and visualizing pitch. Rather than evaluating isolated notes, the app tracks intonation continuously, showing how each tone lands within a musical context. It brings this capability to iPhone users who want deeper insight into tuning than standard chromatic tuners provide.

Operation and display

By recording a performance, RTTATuner plots the tuning of individual notes on a live-updating graph, giving an instant visual of pitch deviations across phrases or entire scales. This continuous analysis is especially useful for instruments with flexible pitch—such as the flute—where single-note checks don’t reveal the full intonational picture.

Main features and strengths

• Generates printable reports (PDF) so analyses can be archived or shared
• Lets you pick from preset temperaments or build your own custom temperament
• Shows pitch in real time with an interactive, updating graph display
• Includes selectable note filters and display options to focus on specific pitches
• Permits changing the reference pitch (A440 and other standards)
• Supports gradual temperament transitions for works that modulate tuning systems
• Suitable for both practicing musicians and instrument builders who need precise measurement

Who it’s for

RTTATuner is aimed at a broad range of users: from students and performing musicians to luthiers and wind-instrument makers. Anyone interested in detailed intonation feedback—teachers diagnosing tuning issues, performers refining ensemble blend, or makers validating instrument behavior—will find the analysis and export capabilities useful.

Customization and export

• Adjust the pitch reference and temperaments to match historical or experimental requirements
• Filter notes or ranges to concentrate on trouble spots or specific passages
• Tweak on-screen preferences so the visual output matches your workflow
• Export session summaries and graphs as PDFs for documentation or study

Alternative option

If you’re exploring other paid audio/music apps, a popular alternative is Punjabi Radio (paid Punjabi songs), which provides curated Punjabi music content rather than tuning analysis.
