Audio encoding changed, truncated audio files

[artisticforge .]

Hello

After several hours of debugging i believe that the cause for the
truncation of many of the Sunday morning radio programs that i listen to
is the change in the encoding software version.

below is one example:

Rod_Whiting_-_1365._2016-09-11_p045pzy5_original.m4a:
Track Type Info
1 audio MPEG-4 AAC LC, 76.800 secs, 320 kbps, 48000 Hz
 Name: Rod Whiting: 2016-09-11
 Artist: BBC Radio Lincolnshire
 Composer: BBC iPlayer
 Encoded with: Lavf56.40.101
 Release Date: 2016-09-11T07:30:00+01:00

Rod_Whiting_-_1363._2016-09-04_p045j3cw_original.m4a:
Track Type Info
1 audio MPEG-4 AAC LC, 5600.000 secs, 320 kbps, 48000 Hz

 Artist: BBC Radio Lincolnshire
 Composer: BBC iPlayer
 Encoded with: Lavf56.25.101
 Release Date: 2016-09-04T07:30:00+01:00

other programs truncated:
Sunday_Worship_-_The_Power_of_Peace_b07tqs7n
compared to
Sunday_Worship_-_Phoenix_from_the_Ashes_b07sxhwz

Hymns_on_Sunday_-_168._2016-09-11_p045qbps
compared to
Hymns_on_Sunday_-_167._2016-09-04_p0451xzh

I will provide others if requested.

There are only two programs which were not truncated

Lincolnshire Farming appears to be ok. I have not listened to the program.

The downloaded file are within nominal file size, it is after
conversion that they are truncated.
