I am new to MusicBee. After using iTunes for many years it was time for a change. BUT the problem of STUTTER that I had occasionally experienced under iTunes was a lot worse with MusicBee. I eventually found that the BIG problem was the ADBLOCKER plugin in FIREFOX.
Most posts under the MB forum suggest changing the latency settings -> Edit Preferences - > Player -> increase buffer size > or load entire file into memory. This got rid of most of the stuttering for me but not all.
I am not an expert, but the issue of stutter (for me) is related to the use of resources 1) MusicBee seems to need more resources than some other MediaPlayers 2) the media player has to compete with other programs for resources 3) other programs on your computer may be hogging resources and causing the stutter 4) Bluetooth and USB hubs/devices may also be hogging resources.
In an attempt to resolve this issue, I first tried different USB set ups - this can reduce the frequency of stutter were several USB devices hocked up to the PC particularly with a USB Hub. Then I looked at Bluetooth. I have a Bitiwend mini Bluetooth stereo amplifier through two Wharfedale bookshelf speakers. The sound is much better with the amplifier connected through the headphone output of the mini PC rather than Bluetooth. The Bluetooth drivers on the PC do not allow such good output quality and positioning of the amplifier (BT receiver) can have an influence. The Bitiwend can also be connected by USB and this option increased stutter.
But though I could reduce the stutter drastically, it was still there now and again. I decided it was time to upgrade my mini PC from a Celeron N3150 to a Ryzen 3300U. However, although better again, the STUTTER would still occur - NOW MOST NOTABLY when opening new browser tabs. I decided I needed to look wider than just the MB forum - and I was even considering an alternative media player. Luckily, I discovered this EXCELLENT VIDEO ON SOUND PROBLEMS here:
https://www.youtube.com/watch?v=q6jdXrdYUsg&list=WL&index=53&t=25sRight at the end of this video it mentions that ZONEALARM and ADBLOCKER (both of which I was using) may cause problems. ADBLOCKER was the primary suspect (it really hogs resources) - and low and behold - after quickly UNINSTALLING ADBLOCKER = PERFECT SOUND. I am really glad I persevered with this as MB is a fantastic music player and so much better than iTunes.
Two other TIPS FOR ANDROID : MB doesn't have an Android version, but I had DoubleTwist on my mobile (previously synced with iTunes). DoubleTwist has a much better user interface and display of your music library than most Android player. I transferred my MB music by USB to the Music folder on my mobile - and DoubleTwist picked up the whole library automatically and works perfectly. This is much quicker than previously using the DT snyc App on the PC - and it is better and cleaner - previously not all artwork was picked up and I often had to edit metadata on my mobile to stop albums being split up.
MusicBee Remote is also a fantastic App to use to remotely control MB on your PC from the comfort of you sofa :-). I hope this helps!
