Here are some things I'd like. But I'm only interested in audio. I know JRiver has extensive "video" functionality but it's not what I'm mad about. Most recent major upgrades have been mostly concerned with video. If there were more improvements in audio fidelity and functionality then I'd be more inclined to upgrade too.
I want better sounding playback. No I don't know how to achieve it. But there's more to it than bitperfect reproduction and memory play, good though they are. I believe in reducing computer services not needed for audio, reducing latency in various ways, refreshing files, lower jitter, etc. You can argue it's not JRiver's job to do this.
I want to edit metadata and add new metadata fields. I know there are ways to do this in JRiver but feel it could be made easier. For example a grid-like presentation of selected tracks where we can change multiple rows at a time, eg to change the genre of 3 tracks by selecting the cells and pasting.
I'd like additional metadata (say integration with allmusic) to get relationships between artists/tracks/genres etc. I'd like to navigate based on metadata. Eg I listen to a track, I list the players and select to see what else the guitarist has played on and then play a selected track. I'd pay extra for this but not roon prices, and I want better fidelity.
Reporting: I want to be sql to interrogate the library and output the results to a csv. I never looked at the internal format of the library but maybe an api could be produced. Ok I can fiddle with smartlists but sql is (mostly) unambiguous and there are tutorials.
I used to love squeezbox ease of finding and replaying internet radio stations. Why can't jriver do this?
Oh, and the wiki - where knowledge is posted, lost and not updated. This is a serious wealth of knowledge that has been let slip over the years. You JRiver guys spend a lot of time helping us in the forum, but there's never enough time.
I'm a long-time member of the JRiver community and only want to help it become even better.
Well you did ask....
