sound library?

[jt916]

Newbie questions,
I recently land a job sound design for a short film for tv here in Asia. I usually work with 48khz samples sound fx's. I want to buy some great sound online but most of them are in 44.1khz and not so great.

I don't like to convert 44.1 to 48, is there sync issue if I do this?

recommendation on which sound library worth to buy, my boss is paying for it as part of the film budget.

thanks

hi there,

there are already a lot of threats concerning sound effects libraries so do a quick search and you'll have a lot of tips...

What's concerning the 44,1 and 48 kHz issue there will be no sync issue at all when converting the regular way... when you work in

ProTools for example the conversion is done by the program and you don't have to worry about it.

The quality of the conversion depends on the algorithm but the one used in PT is more than adequate for the job.

The reason why most SFX-libraries are in 44,1 is because of the fact that the libraries were originally distributed on

CD's in the pre-broadband era and most banks are that old...

Kind regards from Belgium

Pedro

quite honestly, with Sound FX you don't really need to convert 44.1 to 48 just reference the audio and it will play slightly faster and slightly higher pitched, but you'll never notice with FX and Design sounds. Music you'll want to convert of course, but I would rather have my winds and Birds and Whooshes play slightly faster then do a SR convert.

I don't know much about cars in general, so I also resample car engines - there are many guys out there that are nit-picky about anything cars.

To each his own I guess. I want the cue I heard in the library, not the cue I heard faster, higher pitched and shorter. Any decent SRC will be inaudible on most library SFX.

Yeah, but you have to wait for the damn thing to convert! (To each his own)

Pro Tools will force you to copy/ convert.

As it should- I personally would NEVER use master files in a editorial session.


but thats just me....


Sample Rate conversion is pretty fast generally- I have to do it because I have quite a bit of 96k material


YMMV

So, if you want to copy the file to the project audio folder on import (vs just linking to it), PT will force you to convert it?

Or it will force you to both copy & convert (ie you can't link)?

PT doesn't support mixed sample rates, mixed bit depths, or interleaved stereo files so it will copy/ convert in those situations.

I agree with Charles, anyway. I would usually want to SRC anyway in most cases. Soundminer does a good job of it.

You can use Elastic Audio in PT7.4 to change the pitch issue - just stretch the sample out - I'm sure it will slow somewhat after being 'elasticised' thumbsup

Why on earth would do that? seriously- It is like running your recordings through a reverb because you truncated them -


weird.....

I have to agree with Charles and a few others that have posted. The way I work, (and most editors and supervisors I've worked with) is to have a library with mixed bit/sample rates (CD's at 16/44.1, and custom recordings at 24 bit/48,96,192, .wav, .aif, .sd2, mono/2 channel/6 channel, etc.), and use a database program like Soundminer to convert/copy/spot in the files into whatever your final work session's format is, usually 24/48 .wav files in my world. Sample rate conversion on modern computers these days is so fast, and high quality, there's little difference in time when compared to just copying it over. Maybe creatively you'd want to play back at a different speed from the original, but those times are rare.

It was a joke!!

This is not true. If the file you're importing is at the same bit depth but a different sample rate you can hit "add" instead of "convert" and it will just play it at the session's sample rate regardless of the file's native rate.

I'd say I play fx at their original rate less often than at whatever pitch sounds good to me.

Try my Fx site. Most of the fx are in 48khz.

OK, but I guess his statement is true in practice, because people usually work at 24bit, while the majority of libraries are 16bit.....
