Ratings and reviews

the wav file does not appear on the phone. trying to share it to Google drive , nothing happens. you get no file. Update: looking at their response to another review I found the file on my phone , but I thought it wasn't on my phone because it wasn't with the other new audio files. Developer, you should let the user choose the folder because this makes no sense

It's simple, effective, easy to use but it could be better. Scope:: 1. Must be able to record in background 2. Volume change function for rec audio 3. Trim and play in loop a part of recording and share/save 4. Should be able to save Equaliser setting 5. Should be able to share/save the modified audio with equaliser effects instead of acting just as a music player's equaliser 6. Must be able to record on a separate channel without mixing internal audio playing in background.

I did interview and recorded the voice with this app. At the end of almost 2 hours of conversation, this app only recorded 10 minutes of it. There is no information anywhere and it is not possible to find where are the rest of recordings gone. Horrible app

What’s new

- Improved the display speed of the waveform/spectrum display screen.
- Added a feature to display dB and frequency values ​​at the tapped location in the spectrum view.
- Added a “1/24 octave” option to octave analysis.
