KVR Audio

i wonder as i always thought 44.1 kHZ and 24bit is enough but more and more say especially for sound design, making music/sounds for games etc. that 48 kHZ is a must.

1. is it true?
2. how much impact on the performance (PC/MAC) does it have?

1. Don't know. DVD Video uses 48kHz, CD audio is 44.1kHz
2. In theory 8.84% extra.

Yes 48Khz and by now even 96Khz is required for games work.(Latter for the latest highend consoles)

If you use the right sample rate convertor, you can produce in 44.1kHz 16bit, supply it to them in 192kHz 64bit, an no one will notice.
That is, until they watch it with a scope and see there's nothing above 22kHz and below -96dBfs.

Solely for music production 44kHz 24bit
For anything to do with film, gaming etc 48kHz 24bit

thx a lot guys, but e.g. your music is used in a movie, and you produced it in 44.1 KHz what then ?

44.1 kHZ and 24bit

They'll probably just convert it to 48 kHz

Indeed. 44.1 for music and 48 for film is referring to the delivery format, not the DAW sample rate. It's not about the theoretical extra quality: it's just the 'native' sample rate of the playback devices. It's only relatively recently that lossless surround sound has become available in the home. The older lossy standards like Dolby Digital would have lowpass filtered everything well below 20kHz as part of the encoding (AFAIK), but the delivery format was still 48kHz.

Most sample rate converters are good enough to do 44.1 -> 48 and 48 -> 44.1 conversion with less than -100dBi distortion for frequencies under 20kHz. This means that if you deliver the wrong format for music or film, they'll just convert it without worry. Should you work in 44.1kHz to save the 8% CPU when you know the delivery format is 48kHz? Completely up to how "purist" your mood is.

So what's the point of using 24 bit, when the target will be 16 bit in most cases?

Edit: Nevermind, found a pretty good post in German explaining the topic: http://www.tonstudio-forum.de/index.php ... #post15772

Mastering can easily steal 20dB+ of headroom from your tracks in quiet/dynamic passages. And 1 extra bit = ~6dB lower noise floor. Also, when you mix multiple tracks, their noise floors accumulate.

I can't get into your german site but I'm wondering if it says the same thing I'm gonna say, that I can hear(albeit modestly) the diff between 16bit vs. 24bits but can't hear a lick of difference between 44.1khz vs. anything above that. Maybe others can but . . .

peace

Tl;dr, it basically said what vortico wrote in his last post.

48 kHZ or 44.1 kHZ ?
