RecAll is a sound-activated recording tool. Its interface resembles that of a standard recorder; however, you´ll soon notice there’s a slider labeled Vox. This tiny control makes a big difference because it lets you set the threshold audio level at which the program starts recording. This way, the tool becomes appropriate for situations in which sound pauses are not meant to be recorded. This slider requires lowering the threshold level to zero if you want to disable the sound detection mode. Needless to say, this can be confusing for most users and an adjacent checkbox would have been far more convenient.
The tool can work in various recording modes. First, you can use for manual recording, with practically no difference with a standard recording. Second, you can set a specific time for the recording to begin. Third, there’s the already mentioned voice-activated recording. Finally, in echo mode, the last part of every segment is repeated whenever silence is detected. This makes the tool useful for practicing foreign language pronunciation. Luckily, the recorded files can have a very small size, provided a format that allows compression is used. In this regard, ACM markedly reduces the output file´s size. Another advantage is that the tool generates time stamps, which allows going straight to a given point during playback.
In general, RecAll is very convenient for multiple uses. It can be used together with a radio scanner to record signals. Moreover, since the tool can ignore silence, it can be used to take dictation or record notes and ideas. This makes it suitable for audio surveillance as well. Regrettably, it has multiple limitations if sound editing is required.
