Question dongle dac usb in 32 bits, 384000 Hz

[jobas77]

Use dongle DAC in 32 bits, 384000 Hz generates many heat and little expectancy useful life of device? i have VE Odo

 

[MaxwellsEq]

Possibly

32 bits, 384000 Hz generates more heat and less expectancy life of dongle dac and iem?

If it's not too hot to touch I wouldn't panic. If it is too hot to touch it might cause a fire!

If it dies without starting a fire you can just replace it with something else.

I wouldn't expect so. But apparently you have it so you can test with an MP3 or "CD quality" file to see if it runs cooler.

Lower impedance headphones may cause it to run hotter and it may run hotter if you listen louder. Try it with nothing plugged-in and/or with no sound.

FYI - You don't need 32-bits or 384kHz (except for DSD which is has a high "sample rate"). And regular music isn't distributed as 32/384. The pro studio standard is 24/96.

For audio editing, 32-bit (or sometimes 64-bit) floating point is standard because processing is "easier" in floating point and floating point can go over 0dBFS temporarily while editing without Clipping.

I don't think there are any DACs that have even 24-bits of useable resolution. 32-bits is only possible in the digital domain, not in the real-physical world. The usable resolution is limited by noise. If you're not hearing noise it can get measurably better but it won't sound better. The sample rate limits the high frequencies. (The audio can't exceed half of the sample rate.) 44.1kHz or 48kHz can give you the full audio range. You only need higher sample rates for scientific non-audio applications, or for bat "sounds", etc.

what better frequency for mp3 player musics in windows 10 and youtube audio music? i use KZ EDC Pro and VE Odo

44.1kHz at 16bits will be fine.

not found this option in ve odo, 16 bits 48k

I'm only suggesting MP3 for testing because it's not high-resolution. You won't be "stressing" the dongle at anything close to 32/384 so you can test to see if it runs cooler.

I'd be surprised if that makes a difference in heat.

Fine. Better than your hearing.

Most audio has a 44.1 kHz sample rate. Set your unspecified operating system to this value. Bit depth is the arithmetic precision of the data path between media player and DAC. Max it out.
If you are on Windows, check if the spp support WASAPI in exclusive mode. If so you can ignore the Windows defaults

What i choose good best sound no heat generates reduces expectancy life dogle dac in Ve Odo and edc pro?
