Add 24-bit analog warmth and compression to your digital audio and make your music HOT! Forget about spending your money on expensive, analog equipment to produce a warm sound before digitally recording your music. AIPL WarmTone allows you to apply the same analog warmth and compression to music recorded directly on the PC.
