Musicians and Sound Engineers. Musical Notes and Frequencies and Wavelengths. Now there's an app from dgApps to convert between them all. The app features a sliding fader to dynamically change frequency, wavelength and musical note, with locks to step through standard third octave frequencies or whole musical notes. There's a built in oscillator so you can hear the frequency, and a frequency tracker so the app can tell you the frequency. Both the oscillator and the frequency tracker display the audio waveform. A settings section allows for different tuning standards, and variations in the speed of sound. Lambda can also receive calculated Speed of Sound in Air values from another dgApps app, Cair. Lambda is now a universal app, equally at home on an iPhone as on an iPad. In Split Mode on an iPad device, side by side with Cair, the calculated Speed of Sound in Air is passed in real time to the Lambda app. Lambda allows you to share frequency/wavelength/note data via all the usual sharing methods.

Verdict

The call

The clearest difference is update cadence: EZAudioCut at every 2 months against Lambda's every 54 months. EZAudioCut also leads on ratings volume (138 vs 1). Lambda's advantage is rating (5.0 vs 4.6) and price ($2.99 vs $8.99). On review sentiment, ads, in-app purchases and device support there is nothing between them.

Lambda costs $2.99 and EZAudioCut $8.99 up front. Neither carries in-app purchases, so what you see is what you pay.

ReceptionRating · Positive reviews · Number of ratings

Lambda holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: EZAudioCut has 138 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 80% of Lambda's written reviews are positive against 84% of EZAudioCut's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Lambda ships an update every 54 months, EZAudioCut every 2 months. The most recent releases landed on September 17, 2026 and October 5, 2026 respectively.
