Please add Crossfeed

Recommended Posts

Please add Crossfeed option. Please don't get rid of Volume Steps feature, and please and auto sample rate changing.

Thank You

+1

Tried it on Neutron, works better for headphones than StereoX IMHO

+1 UP!!

Poweramp is an excellent player, however an adjustable CrossFEED is one major "must-have" feature still missing.
Believe me. Once you've tried it, you cannot anymore listen to music through headphones without it, as it greatly reduces listening fatigue caused by the exaggerated stereo separation. Music produced to be listened to through speakers (i.e. pretty all music except some binaural mixes) sounds much more natural with a slight amount of crossfeed. This is the sole reason why I continue using foobar2000 despite its numerous shortcomings (no "double/triple click" headset commands to skip tracks, missing album arts can't be downloaded, unpleasant UI, custom skins not working on Android…).
A crossfeed feature would definitely turn Poweramp into the almighty killer of all Android music players! Please consider it.

Note to the developer: If you feel the BS2B implementation (like in Neutron) looks too complicated to be controlled with an easy UI (since you have to set the feed level AND the cut-off frequency of the underlying filter), please check the Meier version that only needs a single cursor/knob. Again, just have a look at foobar2000.

A proposal as to how this could be done without much changes to the UI :

- use the existing StereoX knob, default would be the middle position, meaning "Off"

- turning it to the right would switch on and increase StereoX

- turning it to the left would switch on and increase crossfeed

There are 3 typical settings provided together with the BS2B crossfeed. They change the 2 parameters by increasing the one and decreasing the other. Shouldn't be too problematic to implement that with a single control.

I used to play a bit with those settings. All 3 presets shown above are too much if you just want to ease that annoying "stretched inside your head" feeling and don't try to emulate real speakers (which is a lost cause anyway...).
I personally use a 'minimal' setting on the Meier crossfeed (1 out of 10 or 15/100 depending on the version) but it still helps a lot compared to no crossfeed at all!

As suggested by blaubär, you could very well use the already existing StereoX knob but I guess you would loose some precision. By the way, you want to have enough steps in the lowest values area; more extreme settings sound more or less the same and are pointless.

Technical reminder: keep in mind that in the given BS2B example, the strength of the crossfeed decreases when the "level" labeled setting is raised. So higher dB values will produce a lighter effect.

Why would that be ? Yes, Crossfeed does simulate only a tiny part of the effects real speakers have. But for example Samsungs Sound Alive has an option that promises "Fat Surround Sound". Not that I would like to have that "Fat" sound, but it shouldn't be impossible to simulate room acoustics by adding some reverb to the crossfeed.

Of course you can add multiple effects to psychoacoustically reproduce the sound of speakers in a room (time-controlled echo, HRTF, phase shifting, etc.) but I still have to find a convincing formula. Did you?
Anyway it wasn't my point and absolutely not what I'm looking for. I generally hate those "surround" reverb effects and my philosophy has always been to apply as little signal transformation as possible. The more complex you get, the less reliable the results... and it can quickly become an audiophile nightmare!

I'm not opposed to such an option but I don't think it should be considered as a priority. I believe it would be more judicious to start with a simple crossfeed which should be easier to implement and which is what the typical "speakers listener" is waiting for. (BTW, a "simple" crossfeed doesn't mean "put X% of left signal into right channel" otherwise a low-cost gear with a poor channel separation would do the job!)

Crossfeed is a must have. I use fb2k when listening through headphones, because some albums stereo separation is just terrible for the ears.
