Hardware solutions
High-quality microphones
Investing in a good microphone can drastically improve your audio quality. Look for microphones with built-in noise-canceling features to minimize unwanted sounds. These microphones offer clearer audio capture and built-in noise reduction features, making them durable and reliable. However, they can be expensive and require proper setup and handling.
Pop filters and windshields
Pop filters and windshields help reduce plosive sounds and wind noise, making them essential accessories for both outdoor and indoor recordings. They are affordable, easy to attach, and effective at reducing plosive sounds. Despite their limited noise reduction capabilities, they enhance the overall audio quality when used alongside other accessories.
Soundproofing equipment
Using soundproofing materials such as foam panels and blankets can help reduce echo and background noise in your recording environment. These materials significantly reduce background noise and improve overall sound quality. They can be customized for different spaces but may be time-consuming to install and can be costly.
Digital audio recorders
High-quality digital audio recorders often come with built-in noise reduction features and better audio capture capabilities. These recorders provide superior audio quality, portability, and advanced noise reduction features. They are more expensive than basic recorders and require some learning to use effectively.
These hardware solutions, combined with effective software like ElevenLabs' voice isolator, can help you achieve professional-quality audio recordings.

Additional tips for reducing background noise
Achieving clear audio isn't just about using the right software or hardware. Implementing good practices during recording can significantly reduce background noise. Here are some additional tips to help you create clean audio from the start.
Choose the right recording environment
Aim to record in a quiet space, away from high traffic, machinery, or other sources of unwanted noise. This natural reduction of background noise requires no additional equipment and can greatly improve your audio quality. However, finding such a quiet environment isn't always possible. In such cases, consider soundproofing your recording space. Investing in materials like foam panels, curtains, or blankets can help absorb sound and prevent echoes. While this can be costly and require some installation effort, the significant noise reduction and improved sound quality make it worthwhile.
Use high-quality equipment
A good microphone can capture much clearer audio, especially if it has noise-canceling features to minimize unwanted sounds. Though high-quality microphones can be expensive and require proper setup, their durability and reliability are valuable. Additionally, utilizing pop filters and windshields can help reduce plosive sounds and wind noise. These accessories are affordable, easy to attach, and essential for both indoor and outdoor recordings, though they offer limited noise reduction capabilities on their own.
Apply post-processing techniques
Applying noise reduction filters in editing software like Audacity, Adobe Audition, or ElevenLabs' voice isolator can effectively clean up your recordings. These filters allow you to customize settings for optimal noise removal, although the process can be time-consuming and requires familiarity with the software. Manual editing to remove specific noise segments can also be very effective. This labor-intensive method offers precise control over noise removal, ensuring enhanced overall audio quality.
Monitor and adjust input levels
Properly setting your recording device's input levels prevents distortion and optimizes sound quality. This requires careful monitoring and can be challenging for beginners. Wearing headphones while recording allows you to catch unwanted background noise in real-time, enabling immediate adjustments. Although wearing headphones for long periods can be uncomfortable, this practice ensures immediate noise detection and allows for real-time adjustments.
By following these tips and combining them with effective software and hardware solutions, you can significantly reduce background noise and achieve professional-quality audio recordings.
