App Description

Output from mic to file or headphones with custom delay. Zero delay NOT possible

Designed for:
- Training vocal projection
- Practicing pronunciation at language learning
- Practicing for casting
- Testing headphones
- Recording with audio monitoring
- Recording multiple takes with quick replay of last recorded segment
- Anything else you might want to do with given feature set :)

NOT suitable for:
- Use as a singing microphone with loudspeakers
- Use as an interface with near-zero latency
because
* It is not possible to completely remove the latency on Android devices
* The microphones are typically omnidirectional and pick voices from surrounding, thus leading to loud feedback loop if using loudspeakers

Feature set:
- Output from microphone to speakers or headphones (monitoring)
- Custom delay on monitoring
- Audio recording in compressed or uncompressed format
- Quick replay of the latest recorded file
- Quick sharing of the latest recorded file

Notes:
- When monitoring, you need to make sure, the mic is not picking up the sound from the speakers (i.e. the use of headphones is recommended), otherwise the feedback loop starts producing noise!
- Minimum latency (delay) depends on the audio driver and device specifications. The app is designed to offer the lowest possible latency an app could offer, but there is inevitably going to be some latency on android devices (at least for now).

Free version allows for 3 h of total recording or monitoring time. After that the recording or monitoring session is limited to 1 minute.
