1.15 Record audio

+ +Use this button to toggle audio recording. Start or stop recording becomes effective only when the dialog is closed with the "OK" button. + +

1.16 Select recording output file

+ +Click on the open file icon to open a file selection dialog that lets you specify the location and name of the output files. + +Each recording is written in a new file with the starting timestamp before the `.wav` extension in `yyyy-MM-ddTHH_mm_ss_zzz` format. It keeps the first dot limited groups of the filename before the `.wav` extension if there are two such groups or before the two last groups if there are more than two groups. Examples: + + - Given file name: `test.wav` then a recording file will be like: `test.2020-08-05T21_39_07_974.wav` + - Given file name: `test.2020-08-05T20_36_15_974.wav` then a recording file will be like (with timestamp updated): `test.2020-08-05T21_41_21_173.wav` + - Given file name: `test.first.wav` then a recording file will be like: `test.2020-08-05T22_00_07_974.wav` + - Given file name: `record.test.first.eav` then a recording file will be like: `reocrd.test.2020-08-05T21_39_52_974.wav` + +If a filename is given without `.wav` extension then the `.wav` extension is appended automatically before the above algorithm is applied. If a filename is given with an extension different of `.wav` then the extension is replaced by `.wav` automatically before the above algorithm is applied. + +The file path currently being written (or last closed) appears at the right of the button. + +

1.17 Record silence time

+ +This is the time in seconds (between 0.1 and 10.0) of silence (null samples) before recording stops. When non null samples come again this will start a new recording. Set the value to 0 to record continuously. + +
