Lambda vs AudioCalc Usage & Stats

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.

AudioCalc

HiFi enthousiasts, Home Theater buffs and audio professionals alike make sure you always have those handy formulas with you. This tool offers you a collection of audio targeted conversion tools. The frequency, period and wavelength converter comes in quite handy for positioning loudspeakers. The band tool helps you setup a parametric EQ. The delay part gives you an insight when setting speaker distances and delays. The volume tool helps you determine the amplifier power required for a given set of speakers. The room modal response tool allows you to compute the room modes present in a room. This is crucial when placing a subwoofer provide correct bass response. It can also be used when designing a room to avoid dimensions that would lead to a poor modal response. AudioCalc works in both imperial and metric units. Simply swipe down to reveal the unit selection view. If you liked this tool, be sure to also check VideoCalc, the companion tool that addresses your video needs.
