EBRANTA Technologies, Inc.
recently announced new digital signal processing technology that enables musicians to receive real-time feedback while playing an instrument or even humming a tune. The company also introduced
eTuner, the first application to take advantage of the new technology, which employs a unique algorithm that EBRANTA says “outperforms traditional complex mathematical methods for calculating frequencies of audio signals.”
eTuner analyzes each note it “hears” and displays the note closest to the pitch it detects. It also shows you the amount of variance between the pitch and the displayed note by indicating what percentage above or below the note your pitch is and whether that’s considered high, low, or okay.
eTuner’s key settings feature allows you to decide which note names will be shown when it detects pitches in that key. If you select a minor key, eTuner will also show you note names for the harmonic and melodic ascending and descending scales. EBRANTA notes that this makes eTuner helpful when practicing scales.
System requirements call for a PowerPC G3 running at 400MHz or faster and 256MB of RAM. EBRANTA’s price is US$34.95 and you can buy eTuner through the company’s Web site.
