incoming call on bluetooth is recorded with wrong speed. recording is played much too fast and sounds like micky mouse.
outgoing call on bluetooth works perfect.
in- and outgoing calls are recorded perfect if you just use the phone.
its on an iphone5
is this a known bug?
I've even published a tutorial (for Skype Call Recorder) to fix this issue. It should be workable in this case too. Let me copy it here:
If you also record your Skype calls with
Call Recorder for Skype, you'll need to know that every single call you make using Bluetooth (both Skype's own (buggy) implementation and using
BTMono SBSettings Toggle) will result in a messed-up recording of your partner: it'll play back much (about five times) faster than should. (No such problems will exist with
your part, on the other hand.)
Fortunately, there's a solution. Do NOT make the app convert the recorded files for you (as was, BTW, recommended in the original article; then, only to avoid echo) but transfer them to your desktop and download the free(!), excellent audio converter app
Audacity (
link). With it, you can quickly and easily fix the problem and, in addition, export the two files in a format that doesn't mix the two (in/output) channels into one, by making it, in cases, far harder to understand when there's a lot of echo.
After starting Audacity: drag in the output file (the one that has the
output in its filename); select
Effect → Change Speed. To compute the percentage you'll need to slow down the output file to be entered here, use the following formula:
-(100-100/(input length in sec.ms/output length sec.ms))
For example, if the (accelerated) output file is 11.745 seconds, while the (proper) input 64.692, you can get the percentage in the following way:
-(100-100/(
64.692/11.745))
The result will be -81.844738, which can directly be entered into Audacity. An example:
After this, you can also drag the input file and export both as a stereo audio file (so that you can keep the two mono sources still easily separatable but can be easily listened to with any audio player) by just setting one of them to be the left, the other to be the right channel:
Now, just export it via
File / Export. (No additional settings need to be made there.)
Note that if you don't change the channels but leave both at Mono, the target file will also be mono with both channels in the same track (this is how the built-in conversion works in the recorder BTW when you tap one of the list items):
