File Size
« on: January 04, 2021, 08:40:30 PM »

My application is recording hour-long book readings.  At this point, it does not include the ability to edit except to set the recording mode to Append, Insert, etc. I am very frustrated that, as the file becomes longer, the time it takes to be ready to record after a "Stop" is more than a minute duration.  This application is replacing a VB6 program which employs the Windows multi-media interface and goes from record to play and back instantaneously.  However, it only saves in .WAV and we need to export in MP3.  I've spent a great deal of time on the new version built around MMSOFT Audio Recorder.  I have eliminated all wave analysis and display, recorded to memory and to hard drive as well as experimented with other ways to speed this up but have failed.  I think I've tried everything in the Audio Recorder documentation but the application remains unsatisfactory.  I hope there is a solution I've not yet stumbled upon.  Can someone please give me the answer?

Hello,

unfortunately recording/editing directly in MP3 format is very time consuming because the encoding through Lame is a sort of bottleneck: the best way would be relying upon the WAV format during the recording session and, once completed, perform a final export to MP3 using the RecordedSound.RequestExportToFile method
.

Hope this helps

Although I need to save in MP3, I have experimented with recording in WAV and then exporting to MP3.  I see little difference in the delay from Stop to Record and back whether my app records in WAV, MP3 or a couple of other formats I've tried.  Next thought?

Hello,

sorry for the delay in answering this question but I totally missed your latest reply.
We are currently working to develop a totally rewritten version of the recorder that will speed up things a lot and that should be efficient also for long recording sessions: we hope to have the new major version delivered by the end of May.

Kind regards

You mention the rewritten application which should considerably speed up loading and saving files.  Has this been completed?
