How to Convert 24 Bit Audio to 16 Bit Windows 10

How do you convert thousands of 24bit samples for 16 bit hardware samplers?

---

I have hundreds of folders with 24-bit samples. I want to convert them to 16bit 44.1KHz and add 100 samples of silence at the front. This is for MPC and Triton extreme. Sounds easy, right? But how do I do it for all the directories without specifying each one? Sound Forge will do it perfectly if you enter each directory at a time. How can I do all of the directories without the manual labor?

What about batch processing in Cool Edit or Adobe Audition?

Doesn't sound right

By default, batch processing is limited to three files at a time for optimal performance. To process more files, change the value for Maximum Number Of Concurrent File Processes in the Data preferences.

A bit of clever googling "ffmpeg" will get it done...

Use Soundforge batch converter here

Install linux.

Then it is as simple as one command line. Just specify "-rf" before the main path and conversion utility (such as sox) it will go in recursively in each subfolder and replace absolutely everything.

SoX - Sound eXchange | HomePage

EDIT: TIL sox is avail for Win and Mac aswell. Well then i guess you just have to install sox.

If you have soundforge then go to the top level folder in windows and search for *.wav
Then copy to a new folder
Then batch convert in sound forge
You may even be able to drag and drop after the search to keep them in the same folder - can't remember
Also experiment with the "keep directory structure" option in the batch converter

Installing Linux is unnecessary, sox however is what I was going to suggest.

You'll need a script to batch process using sox, but either the windows batch language or powershell will do the job just fine, without having to install a whole OS!

Someone also created a sox GUI of sorts that run in Excel:

It generates a bulk commandline for copy/pase into a CMD.EXE shell.

This one used to use izotope src too. Probably still does.

its free for trial for 21 days... i converted 7 Gb samples for my Akai s5000 today in 150 folders in one go (folder with subfolders etc.).. took 14 minutes with 6 cores.

I use foobar2000: foobar2000 to get down to 16-bit 44k. Then I have a powershell script to rename down to 8.3, which I believe is the format my MPC requires.

Yes, I'll go so far as to install linux if it needs it. But inception style, I'll create a virtual machine thanks.

SF is great but it will not do subdirectories. I will have to select hundreds of folders.

No you can't drag and drop. That could have worked if the path was included as well. Darn.

I agree a powershell script to parse the directory tree is my solution. Converting one file at a time repeatedly, just let it go for hours.

This is what I use, as well. No complaints.

... and the winner was dbpoweramp. I didn't think it looked more than a MP3 player, but the convert dialog box has what I need.

I couldn't use more than 1 core because the insert audio file (to get 100 samples space at the front) caused most cores to lock up. So it took 1hr 20mins to convert 28,0000 samples.

Thanks everyone for posting!

I batch process (and two track edit) with Twisted Wave. It's great and it's cheap.

Instrumentalists, you know, guitarists, violinists, saxophonists, drumists, etc., don't know how easy they've got it. You have to be a friggin' A+ certified computer programmer to be an electronic-musicianist.

Or try Waveosaur which also has batch processing

already named, but i'll second the mentions for:
dbPoweramp or Foobar2000
