Frequently Asked Questions
An SP Audio DSP serves multiple critical functions in audio systems:
- Signal correction and enhancement to compensate for acoustic imperfections
- Audio channel management including time alignment to synchronize speakers
- Precise crossover control for multi-speaker setups
- Equalization to adjust frequency response for optimal sound reproduction
- Sound customization allowing users to create personalized audio profiles
These functions collectively result in dramatically improved sound quality, clarity, and imaging compared to standard audio systems.
Parametric and graphic equalizers represent two different approaches to sound adjustment:
| Feature | Parametric Equalizer | Graphic Equalizer |
|---|---|---|
| Frequency Selection | User can specify exact frequencies | Fixed frequency bands (typically 31) |
| Bandwidth Control | Adjustable Q-factor for precise control | Fixed bandwidth for each band |
| Precision | Higher precision for targeted corrections | Less precise but simpler to use |
| Best For | Eliminating specific issues, tuning | Overall tonal shaping, quick adjustments |
Many high-quality DSPs like the Ashly Protea DSP include both types of equalization for maximum flexibility.
Determining optimal crossover frequencies involves several considerations:
- Speaker specifications: Set crossover points based on each speaker's frequency response range
- Driver capabilities: Consider the mechanical limitations of tweeters, midrange, and woofers
- Acoustic environment: Vehicle or room acoustics may influence ideal crossover points
- Sound design goals: Different crossover points can change the character of the sound
Generally, crossovers are set at points where speakers naturally begin to roll off in frequency response, creating a smooth transition between drivers while avoiding potential damage from frequencies outside their optimal range.
Yes, audio delay customization is one of the most valuable features of modern DSP systems. This capability allows:
- Time alignment between speakers to create a coherent soundstage
- Compensation for varying distances between listeners and speakers
