# fianniyのblog#### Tips for finding deals and discountsAcquiring quality audio gear on a budget requires savvy shopping. Here are proven strategies:* ** Monitor E-commerce Platforms:** Sites like Amazon, Price.com.hk, and HKTVmall frequently have flash sales, especially during major shopping events like Black Friday, Cyber Monday, or the 11.11 Sale.* ** Consider Refurbished or Open-Box Items:** Many manufacturers and authorized retailers sell certified refurbished devices with full warranties at a significant discount. This is an excellent way to access higher-tier models.* ** Look for Local Distributors:** Sourcing directly from a ** ** or its official distributor in Hong Kong can sometimes cut out middleman markups. Check official brand websites for a list of authorized dealers in the APAC region.* ** Bundle Deals:** Sometimes, a webcam and speakerphone are sold together as a "home office kit" at a lower combined price than buying separately.### Free and Low-Cost Software SolutionsHardware is only half the battle. Software can work wonders to clean up your audio signal in real-time, and much of it is completely free.#### Noise suppression tools built into operating systems (Windows, macOS)Both major desktop operating systems now include built-in audio enhancement features. Windows 10 and 11 have a setting called "Noise suppression" found under Settings > System > Sound > Input. When enabled, it uses AI to filter out background noise. Similarly, macOS offers "Ambient Noise Reduction" in the Sound preferences of System Settings, which can be applied to the microphone input. These are zero-cost, always-available options that provide a foundational level of noise cleaning. While they may not be as configurable as dedicated apps, they are a fantastic first step that requires no additional downloads or spending.#### Open-source audio editing softwareFor post-production or advanced real-time filtering, open-source software is a powerhouse. OBS Studio, primarily known for streaming, includes a powerful audio filter stack. You can add noise suppression, a noise gate, and a compressor to your microphone source, then use OBS's virtual camera feature to send the cleaned audio and video to Zoom or Teams. Audacity is another free, open-source audio editor perfect for cleaning up recorded meetings or podcasts. Its noise reduction tool allows you to sample background noise (like fan hum) and remove it from the entire recording. These tools have steep learning curves but offer professional-grade results for free.
