Hi
I wish to convert the m4a voice memo files to wav so that I can attach the voice files to the gps track when editing the Open Street Map using the JOSM editor. To do this the time stamp needs to be maintained so that the recording can be aligned with the correct part of the gps track. All the conversion programs I have tried change the time stamp to the time they are modified. Any method? The voice memos app on my iphone 4 works well as it syncs the files to my Imac for easy upload to JOSM but unfortunately records only in m4a.
I have tried other apps that record in wav but to get them on to the Imac sometimes involves sending each sound file individually by email or sending to the cloud and then when retrieving from the cloud the timestamps are changed. On a gps track on my cycle I may record hundreds of individuals sound files.
Initially I thought I would try to convert the m4a files as the syncing makes it easy and quality is fine. A unix or perl script would be great. Or is there a voice memo app that produces wav that can be synced easily so I can upload the files easily.
