使用AVAudioRecorder录制时创建2秒音频文件

Question

i am using AVAudioRecorder to record the iphone input. i need to create a file from the recored every 2 seconds (while recording) without damaging the main file i am recording.

Example:

lets say i am recording a 10 secondes file

------------------
    10 Seconds

during the recording i need to create 2 seconds "chunks" ready to be sent over POST request.

--  --  --  --  --
 2   2   2   2   2

any head start?

Answer 1

to manage this i found out that i must use apple's Audio Queue Services which is ac based API. here is a link

this stuff is really cool!

Answer 2

Do you really need to break the audio file into 2-second chunks for sending over a POST request? Can't you send out the data using multipart form data?

Try using an API like ASIHTTPRequest to send out the audio file over the request.
