A kind of auto audio recorder that automatically starts recording when the sound intensity exceeds the threshold, skipping silence (adjustable between "1s" ~ "40s"), especially suitable for long-time recording scenes, such as snoring or any other breathing activities for health monitoring during sleep ( snore + apnea, cough etc.), dream / sleep talk recording for fun, meeting and class recordings for business and study etc.

It also supports many other functions such as folder management /multiple file sharing, merging and deleting /audio compressor ("wav" -> "m4a", saving storage space) /auto play and waveforms for ".wav" files etc.

💡 Features:

- Automatically skip sounds that are weaker than the threshold, treated as "silent" sounds. The silence duration is adjustable between "1s"~"40s".

- Be able to record in the background, even when the screen is off.

- Recordings are sorted on a timeline.

- Easy to use. Click the power button icon to start, then you can adjust the threshold and silence settings by different usages. The threshold is a reference (1~100) for users to determine how loud the sound is to activate the recorder to start recording, users need to adjust it in real time based on the environmental noise. The silence setting is used to make the weaker sound below the threshold last for a few seconds before stopping the recording automatically in order to maintain the continuity of the sound, the range is (1s~40s).
In short, the threshold is the condition for automatically starting recording, and the silence setting is the condition for automatically stopping recording.
E.g, for snore recording, in a quiet place, the threshold = "4"~"8"/the silence=10s, for talking, in a quiet place, the threshold ="2"~"5"/the silence = 4s+.

- Audio player with auto-play function, highlighting the current playing recording and auto-scrolling etc.

- Powerful recording management, can be labeled as well as shared/deleted by single/multiple/all.

- Folder management, easy to manage unlimited recordings. (for premium users)

- Recordings (.wav) can be merged into one single file. (for premium users)

- The waveform of the ".wav" file can be displayed during playback, this visual pattern can help users tell which files are snores and which are sleep talk. Generally speaking, a snore is a regular wave, while talking is more likely to be irregular. (for premium users)

- Set timer to turn off recorder. (for premium users)

- Audio file converter from .wav to .m4a, saving storage space.

- Save recordings safely in many special cases, such as shut down/low battery/low storage.

For premium users, in addition to no ads, there are some extra features: 1. Unlimited folders. 2. Multi-file merge. 3. Countdown timer. 4. Waveform for ".wav" files. All of these are included in the entire package. If purchased, just open to use, otherwise a message window will pop up. "Unlimited folders" is located on the "My folders" page, expressed as the "+" button. "Multi-file merge" is on the recording file page, expressed as the "Merge multiple files" item. "Countdown timer" is on the home page, expressed as the timer icon.
"Waveform for '.wav' files" is on the ".wav" file player, expressed as the waveform checkbox.

❓Q & A,

Q: How do I use this app to know my sleep habits?
A: The solution is as following, on the first night, set the threshold to 8 (this setting is good for a quiet place, always set the silence duration to 10s here) and check if it can pick up louder sounds than this. If it catches very little, or even nothing, it means that there is no louder sound than the threshold 8 when you sleep, and then drop to 7 the next night, do it again, to 6, ..., until it can catch snoring, sleep talk or heavy breathing etc., certainly it would catch some noises too, just ignore them. After repeating for a few nights, you would know how louder sounds you usually make while sleeping.

Minor bug fixes & Improvements.

Notes:The smaller the threshold, the higher the sensitivity. If the threshold = "0", it just records everything constantly like a regular recorder regardless of the silence setting. In a quiet place, for talk recording, "2" is recommended or adjust ("2"~"5") based on the real-time background noise level, for snore recording, adjust it between "4" ~ "8". The silence duration is adjustable between "1s" and "40s".
