FAQ

1. I cannot record anything any longer.
This happens when the task of VirtualRecorder gets killed while recording in background. You have to restart your phone to reinitialize the record sound system.

2. Is there a way to open mp3s or other formats ?
Not at this time. But you can still export any media file from your PC with a any audio software(like audacity, cool edit etc) to RAW PCM Signed Little Endian 22kHz 16bit mono format and put it to your sdcard with ending .pcm.

3. Is it also possible to do a time shift without modifying the pitch shift ?
No, perhaps it is in future versions.

4. How do i export my recordings ?
You can export them as ringtones in the filebrowser(the filelist you get after you pushed the yellow button) with a long click. They are saved in /media/audio/ringtones on your sdcard as standard wave files. You can also copy the .pcm files from /VirtualRecorder on your sdcard to your PC and import them with any audio software (like audacity,cool edit etc). See Screenshot for Import Settings in Audacity.(Choose File->Import->Import Raw Data)




Screenshots for Import Settings in Cool Edit:



5. Does importing also work on MAC or linux ?
Yes.

6. Is the format proprietary ?
No, it is "RAW PCM Signed Little Endian 22kHz 16bit mono" with the file ending ".pcm". This is the best compromise of size, performance and quality because android offers no other way to perform this special way of pitching and playing reverse.

7. Why are there no open/save options ?
Because we don't need them. The step of saving is not needed. It is done automatically at recording time. Since there is no way to open other formats than our predefined one, there is no options dialog for opening files.

8. How can i delete my recordings ?
Just Long Press on a recording in the filebrowser(list of .pcm files shown after pressing the yellow button) to open the file dialog where you can export and delete.

9. Can I record phone calls?
not at this time.

10. How can i send recordings ?
When you are in the filebrowser mode, after you pressed the yellow button, you can open files with a short click and open their context menu with a long click. In the context menu you are able to send a file.

11. What can i do if i accidently deleted (all) recordings ?
if you already exported them before as ringtones or sent them as mail, they have been saved to /media/audio/ringtones as wavs on your sdcard.
Virtual Recorder is not able to delete files from /media/audio/ringtones.
if you want to restore the deleted files, immediately stop to transfer anything to the sdcard and stop to download anything.
any write process to the sdcard could destroy them.
best would be to switch your mobile off and take the sdcard out and use a pc card reader for further operations.
they are just deleted in the file system. it is the same as lost photos on a digital camera.
there are several pc software products out there which claim to be able to restore all files accidently deleted on a sd card.
just do a google search for "sd card recovery".
the path of the recorded files on your sdcard is /VirtualRecorder/*.pcm

12. Can I use "FreeMp3Droid" to convert my recordings to mp3 format?
Yes, just use 22050kHz as Sampling Rate Setting in FreeMp3Droid.
