it uses the headphone jack as the ADC. the app is called huskerscope. i made this little board to allow me to have an input
minus-squareglibg10blinkfedilinkarrow-up1·edit-21 year agoI imagine the ADC has a high-pass filter. The low sample rate (usually 48kHz) could also be an issue You can also use your phone as a 2-channel function generator using https://play.google.com/store/apps/details?id=com.keuwl.functiongenerator. Maybe you could use both at the same time to measure a circuit’s frequency response
minus-squareDoubleOwl7777@feddit.deOPlinkfedilinkarrow-up1·1 year agohuskerscope actually has a 2-channel function Generator in it aswell. but duento the filter i now am working on an esp8266 based scope as i had the esp laying around.
