RE: [asterisk-users] sound file length
Good Thinking, the code is only about 5 lines. As to the WAVE RIFF file being funny. Well, you have to know a little about the car you are working on to know if you need metric or Standard wrenches and which dealership to get parts from. But the basic idea works. Some many bytes per second means a file of x bytes of y format is z seconds long. Geez, how accurate does the length have to be? 1.98 is to short but 1.985 is long enough. Asterisk only records in a few formats, GSM, WAVE and something else at times. If you need help, drop me a line and I will help you discover how many bytes makes up 1 second or x seconds... Later.

RE: [asterisk-users] sound file length
If it is a wav file you can take the size of the file in bytes and subtract 44. So if the file is 5 seconds long, and is 16 bit Linera PCM (uncompressed ulaw), it contains 80,044 bytes. Length = 80,044 - 44 = 80, 16,000 bytes / second is uncompressed ulaw, i.e. G.711 8/ 5 = 16,000 bytes per second so if you do this: (size - 44 ) / 16 = time in seconds. (80,044 - 44) / 16 = 5 seconds So if you want the file to be more than 2 seconds to be good. Do this 2 * 16,000 + 44 = 32,044 bytes. So if the file size is greater than 32,000 bytes you have a good file. Any thing less then 32,000 bytes would fall under the 2 second threshold. How you get the size of the file is up to you.

This is a heuristic that may work for many wav files, but is not true for others. A wav file header can be larger than 44 bytes, the wav data doesn't have to start right after the header, and many wav files contain meta data after the wav file data (and techically meta data could come before the audio data, but I've never seen that before). Some very poorly written wav file playing programs will play right through that meta data as if it was audio data.
