Orinj version 5.0.0 was released on April 5, 2020. It contains huge additions and improvements over the previous version. Here they are.
I read a few articles about flangers vs. phase shifters and watched some videos. I found them unsatisfactory. It is hard to tell the difference. Many videos talk about more or less "whooshing", "bright", and "pronounced", but all of that means little to me and depends on the settings. Also, videos contradict each other.
Having designed flangers and phasers, I would say:
Yet another post about Orinj – our software for recording, mixing, sequencing, etc. Yep, so what? I've been spending a good amount of time with it recently, so that is what's in my head. Plus, I want to keep this blog alive while I am spending all my time tinkering with the software.
A decade ago I was traveling to and from Sarajevo and spending a lot of time in boutique hotels and local bars. I made friends with bartenders. I even recorded a song with one of them.
It is usually better if there is some separation between the guitar and the bass. If they occupy some of the same space in the frequency range, one or both will be hard to hear, and the song may become a lot less interesting.
This is un update of an old post – from ten years ago. A post about software ten years ago obviously needs an update, even though, frankly, not that much has changed.

I am testing my compressors. I start with a simple frequency of 400 Hz over the sampling rate 8 kHz. I apply a volume envelope over this frequency. The envelope is simple.
- The volume is zero over the first 400 samples (about 50 milliseconds).
- It increases gradually (a straight-line increase) to 0.9 over the next 80 samples (10 ms).
- It then decreases gradually to 0.4 over the next 1600 samples (200 ms).
- It is sustained at 0.4 over the next 3200 samples (400 ms).
- It decreases to zero over the next 4800 samples (600 ms).
We are releasing version 4 of Orinj.
Beta release of Orinj
This is a beta release.
Beta means that this release has not been fully tested. We do not guarantee that it is stable. Use it if you are adventurous and want to experiment with the new features of Orinj.
When equalizing vocals, much of the work involves removing offending frequencies. We do so by cutting out a narrow band of frequencies.
Typical recommendations are:
- If there is too much low frequency rumble, cut down on frequencies below 80 Hz.
- If the vocals are booming, look for an equalizer that can put a magnitude reducing notch with a middle frequency somewhere between 100 Hz and 300 Hz, dipping down to, say, -30 dB, and a width at -3 dB of probably about 100 Hz. You would have to experiment by moving the notch up and down the interval between 100 Hz and 300 Hz to find the offending frequency band.
I have been testing various sine sweeps for use in impulse reverbs. I thought it would be useful to show the Java code for creating a short wave file with a sine sweep. The code is simple, but also interesting. It is interesting not only because it creates a sine sweep, but also because it shows the structure of simple wave files. Beginner DSP designers, who want to create or read wave files, may find it useful.
