Hi Nakia,
Ok, played around some, and found that while the file is created when you start
to record, it doesn't write any data to it until you stop recording. That's not
going to work, so I came up with a little something that does. It rotates the
file that is being recorded and the file that is playing. Works pretty good,
lol, but there sometimes a slight pop when switching files. Your milage may
vary!
See what you think. It was an interesting exercise!
Put 2 buttons on a card. Name one Record and the other Stop
Out this into the script of the Record button:
global gFileNamePath1,gFileNamePath2,gFileNamePath3
global gRecFileName1,gRecFileName2,gRecFileName3
global gRecPointer1,gRecPointer2,gRecPointer3
global gCurrentFileNum
global gSendJammerID
on mouseUp
#Setup mergMicrophone
if the environment is "mobile" then
mergMicrophoneSetNumberOfChannels "Stereo"
mergMicrophoneSetSampleRate 44100
mergMicrophoneSetAudioFormat "MP4-AAC"
mergMicrophoneSetTargetBitRate 65536
mergMicrophoneSetAudioQuality "High"
end if
# Setup up AV Session
if the environment is "mobile" then
mergAVAudioSessionSetCategory "play and record",false,false,true,true
end if
# Setup file names & current file number
put UUID ("random") into tUUID1
put UUID ("random") into tUUID2
put UUID ("random") into tUUID3
put 1 into gCurrentFileNum
if the environment is "mobile" then
put specialFolderPath("cache") & slash & tUUID1 & ".m4a" into
gFileNamePath1
put specialFolderPath("cache") & slash & tUUID2 & ".m4a" into
gFileNamePath2
put specialFolderPath("cache") & slash & tUUID3 & ".m4a" into
gFileNamePath3
put tUUID1 & ".m4a" into gRecFileName1
put tUUID2 & ".m4a" into gRecFileName2
put tUUID3 & ".m4a" into gRecFileName3
# Start Recording with file 1
mergMicrophoneStartRecording gFileNamePath1
send "playBackJammerStream" to me in 500 millisec
put the result into gSendJammerID # To cancel sends when stop is pressed
end if
end mouseUp
on playBackJammerStream
#stop recording current file, start recording on next, start playing current
file
switch gCurrentFileNum
case 1
mergMicrophoneStopRecording # Stop recording to current file so data
is written to disk
mergMicrophoneStartRecording gFileNamePath2 # Start recording to new
file so you don't lose anything in the stream
put "file:" & gFileNamePath1 into tGetFile # Set up file we just
stopped recording for playback
put mergAVPlayerCreateFromURL (tGetFile) into gRecPointer1 # Create
the AV player for that file
mergAVPlayerDo gRecPointer1,"play" # Start playing file
put 2 into gCurrentFileNum # Advance counter for next callback
send "playBackJammerStream" to me in 500 millisec # Call me back to do
all over again
put the result into gSendJammerID # To cancel sends when stop is
pressed
break
case 2
mergMicrophoneStopRecording
mergMicrophoneStartRecording gFileNamePath3
put "file:" & gFileNamePath2 into tGetFile
put mergAVPlayerCreateFromURL (tGetFile) into gRecPointer2
mergAVPlayerDo gRecPointer2,"play"
put 3 into gCurrentFileNum
send "playBackJammerStream" to me in 500 millisec
put the result into gSendJammerID # To cancel sends when stop is
pressed
break
case 3
mergMicrophoneStopRecording
mergMicrophoneStartRecording gFileNamePath1
put "file:" & gFileNamePath3 into tGetFile
put mergAVPlayerCreateFromURL (tGetFile) into gRecPointer3
mergAVPlayerDo gRecPointer3,"play"
put 1 into gCurrentFileNum
send "playBackJammerStream" to me in 500 millisec
put the result into gSendJammerID # To cancel sends when stop is
pressed
break
end switch
end playBackJammerStream
and put this into the Stop button:
global gSendJammerID
on mouseUp
# Stop recording and cancel the send timer
if the environment is "mobile" then
mergMicrophoneStopRecording
cancel gSendJammerID
end if
end mouseUp
Best,
Steve
