This simple tool adjusts the volume and EQ (bass-treble balance) of a .wav file. It's mostly just a silly experiment, but it can be a useful reference point when mastering or just post-processing tracks. Don't use it on short sounds or single instruments, as it usually work better full mixdowns.

Download

Windows

 Download Auto EQ drop and place it in a folder somewhere. More "styles" can be unlocked by enabling the additional sections in the .ini file.

Download AutoEQ.exe if you prefer the command line then place this in the path, for example in C:\Windows\

OSX

 Download AutoEQ for Mac OSX, unpack and place it in the path, for example /usr/local/bin/
You might have to do a
sudo chmod a+x /usr/local/bin/autoeq
to make it work. Then simply run "autoeq" to see if it's installed.
Remember to use .wav files because .aiff isn't yet supported.

Linux

 Download AutoEQ for linux, unpack and place it in the path, for example /usr/local/bin or /usr/bin.
You might have to do a
sudo chmod a+x /usr/local/bin/autoeq
to make it work. Then simply run "autoeq" to see if it's installed.

Using it

Windows & Linux

 The easiest way to use it is like this:
autoeq "input.wav" "output.wav"

A bit of explanation

The AutoEQ runs through the .wav file twice. First it reads the whole .wav file and finds out what the frequency curve is. Then it inverts that curve, so that anything that's too loud will be attenuated, and things that are too low will get boosted. This curve then gets smoothed a bit to avoid unnatural results. Finally, during the 2nd pass through the audio file, this fixed EQ curve is then applied to the output .wav file.

Command line parameters

Options that can be used for the command line version or in the AutoEqDrop.ini file.

autoeq must be installed for this to work.

A few examples

Standard mode:
autoeq "input.wav" "output.wav"

Old-school sound, might work better for classical music:
autoeq -highpass 100 -classic 65 "input.wav" "output.wav"

Changes

AutoEQ has been re-written from scratch, and is now a 64-bit application that should load both 8, 16 and 24 bit .wav files, stereo as well as mono, 32-96 kHz. 192 kHz is still untested. The meta data in the source .wav file will be retained.
