McDSP, maker of some of my favorite plugins (like Analog Channel for one), has gone and jumped into the iPhone app fray (say that five times fast). I must say, I didn’t see this one coming.
It sure looks and sounds cool! When I finally get my new iPhone it’ll probably be one of the first apps I actually buy, considering there are so many cool FREEeeee ones in the Apple App Store.
It’s called Retro Recorder – Enhanced Mobile Recording.
Here’s the lowdown from McDSP.

ALX (Audio Level eXtension) – What Is It Exactly?
McDSP Audio Level eXtension (ALX) algorithms improve audio recording and playback performance using patent pending techniques derived from McDSP’s experience in professional audio software development over the last decade.
Recordings using ALX can capture up to 30 dB (32 times) more signal than standard recordings. ALX can also isolate close proximity signals from background noise during recording, and minimize volume variations during playback.
Audio playback using ALX provides a better listening experience by maximizing audio fidelity and minimizing volume changes. Playback benefits of ALX algorithms include:
- Minimized music track volume variations
- Noisy environments no longer impacting listening enjoyment of music and movies
- Television and movie manner mode for listening at reduced levels, while keeping loud and quiet parts audible
Because ALX algorithms are highly optimized and have little latency, they can be used for other realtime audio applications such as:
- Maximizing signal levels between cell phone callers
- Better audio fidelity in laptop and desktop computer speakers
- Improved fidelity for internet audio streaming
- Better audio fidelity in computer games and game consoles (XBox 360, PS3, others)
The McDSP Retro Recorder is the first consumer audio product to incorporate ALX technology. Stay tuned for more developments using ALX. Contact McDSP for licensing information.
And then my creative life changed forever.
