This usually happens because kdenlive is not smart enough to deal with multiple types of files, especially different frequency. If you take a 44.1khz audio track and then add a 48khz track, you will definitely get the pops and clicks. Use a tool like audacity or similar to do two things, flatten the audio tracks to mono and at least make sure both tracks have the same frequency. I recommend changing both to 44.1khz. After Idid this and reimported the trac........

In our example we take "sound.mp3" and convert it to .wav. Generally Asterisk for its wave needs one audio channel (-ac 1) / mono and 8000hz (-ar 8000) instead of the standard CD/MP3 of 44100hz. Here is the command to convert into Asterisk .wav format: ffmpeg -i sound.mp3 -ac 1 -ar 8000 sound.wav Errors Asterisk may give you if the format is wrong: -- Executing [91781891@cme:3] Playback("SIP/234-000........

Sometimes due to your BIOS/EFI you may find that you have chosen "Energy Efficient" for your CPU which may effectively disable turbo mode. This is because "Energy Efficient" will often restrict or throttle your CPU to the base speed. This can impact nearly any CPU such as Intel's, AMDs, Opteron, Xeon etc... This is of course frustrating, for example if you have a CPU that is 2.0GHz base speed but turbo to 2.5GHz, you will never hit more than 2GHz.........

ID3 2.4 can cause various MP3 players, especially on vehicles or even computers, not to play or at least not to display the ID3 tags. In many cases though, since ID3 2.4 is much different than version 2.3, it will cause some players, especially in cars like Lexus not to play. Even on the computer, you may notice if you check the properties of the MP3 that it won't open or show any details (eg. frequency, bitrate and ID3 tags). One symptom of this in a vehicle (eg. Leuxs,........

I used to believe that for Desktops especially that the "ondemand" CPUfrequency changing that kernels included with Ubuntu and Debian based distros have would be sufficient for snappy performance. However, you can feel the lack of performance on the fastest computer if you have ondemand. A lot of times even under high load 100% of your CPUfrequency in MHz will not be used. For example a 2.8Ghz CPUmay only run at 1.8MHz or even .9GHz. Now........

The problem is that the default of most of these units is set for non-North American phones so the ring sounds like it cuts off and is not sequential. How To Fix the Issue Click on "Regional" and make sure you are in Advanced mode. ........
