Increasing Pitch on Audio Players

[Trdat]

When increasing pitch on any audio player such as Jriver or any other device the music turns strained or just doesn't sound as good as the original BPM. But when a DJ speeds up the BPM on his decks you don't get the same effect barely noticing that the speed/pitch difference till put in comparison then you can tell the BPM has changed. However, the sound quality isn't really effected and doesn't sound strained as it does with music players in general.

Any thoughts on this would be appreciated...

There are algorithms used in studios that do this very well. Adjust speed without changing pitch and vice versa. Or change both. Within reasonable extremes; you can't set playback to 0.1x without getting some bizarre effects on tone/timbre.

Do you mean "pitch" which is about adjusting frequency (e.g. making the note C into C#), or speed (i.e. making a 3 minute song into 3 minutes and 10 seconds). They are two different things.

In the days of analogue tape and LPs, if you slowed the tape or LP down, the song took longer, but the pitch dropped as well. With digital processing you can speed a podcast up without pitch change or change the notes without changing timing. DJs often change the BPM without changing the pitch. Less frequently, they change the pitch.

My apologies I meant tempo. But at least from the terminiology I know to increase the BPM.

My question is how a DJ can change the tempo without changing the pitch but when I change the tempo in Jriver its obvious something is wrong with the track.

I swear the radio stations over here are getting out of hand with tempo changes to 'fit' a song in before the news on the hour, etc. Drives me mad as I am very sensitive to both pitch and tempo, but even digital tempo changes result in my annoyance.

they have an option to re-pitch when warping (which means bpm changes). It can be set to work automatically.

In JRiver try the "Tempo" adjustment under Tempo and Pitch. https://wiki.jriver.com/index.php/Tempo_and_Pitch

I use that, but you can still tell that something has happened to the track. Its okay, I just thought it would be better.

if you need something better, look at Serato Pitch'n Time https://serato.com/pitchntime

What I would really like is a program that can slow the track down to my desired BPM and then set and imported back into Jriver so I don't have to muck around with the BPM on the fly in Jriver. Any ideas how that can be done?

What you're looking for would be a tool/plugin for Jriver that could read a modifier/flag/command added to a filename containing the processing instructions for that file. The plugin would then read the modifiers from the filename and apply these modifiers on the fly using JRiver's Tempo and Pitch contols during playback without altering the contents of the file.
I don't know if anything like this exists.
Of course you would have to populate the flags manually or with a tool able to do so, first.

Alternatively, nothing prevents you from using e.g. Serato Pitch'n Time to process the files to your desired pitch and tempo and then output a new file that you could then replace your orginal with.
