PocketSpeakerCheck is an Android app for quick, repeatable loudspeaker and room measurements. It plays a logarithmic sweep through a Dayton Audio iMM-6C's DAC into an amplifier and speaker, records it on the same iMM-6C's calibrated microphone, and deconvolves the impulse response. It is for hobbyist speaker builders who want a measurement rig made of a phone, a USB microphone and the amplifier they already own.
In a browser the app runs against a simulated speaker, so every screen can be tried without hardware at https://psc-app.rkroll.com.
