Make Your Mixes BiG!

Get to know them!

Stereo image is of utmost importance to the quality of a great mix, but many tools geared toward expanding stereo image often introduce unwanted phase shifts, cancellations, and comb filtering. Painstakingly modeled from the 2024 TEC Signal Processing Award–winning hardware, Brainworx SPL BiG processes stereo input with a unique filtering network that differs from standard mid-side processing, thereby preventing all these issues (though it features mid-side processing and metering options as well). Additionally, SPL BiG lets you add analog tone and does everything with only five controls and an extremely small CPU footprint. Finally, SPL BiG's AirBass EQ is derived from the SPL IRON mastering compressor with plug-in-only features such as Panorama controls and automatic gain compensation.

Extremely intuitive control scheme

With only three knobs and two switches, SPL BiG couldn't be simpler to use. Range control adjusts the filter frequency for exacting control over the range you'll be processing. Stage control makes important mix components feel more present or subtle due to how it manipulates the slope. Finally, the Bigness control does exactly what you'd expect. This unique dry/wet mix knob blends processed and original audio with SPL's proprietary method, allowing you to parallel process with precision — all free of unwanted artifacts.

Modern workflow features

Using a passive filter inspired by the AirBass circuit in the SPL IRON mastering compressor, the AirBass EQ essentially acts as a bass boost function. Plus, SPL BiG from Brainworx offers plug-in-exclusive features like Panorama controls, automatic gain compensation, and mid-side metering and mid-side solo functionality. Altogether, Sweetwater studio engineers love the depth and ease of use that SPL BiG awards them.

Otherwise, an invoice that meets the minimum purchase amount and contains at least one qualifying manufacturer product is eligible for promotional financing. No interest will be charged on promo purchase balance, and equal monthly payments are required on promo purchase until it is paid in full. The payments equal the amount financed divided by the number of months in the promo period, rounded up to the next whole dollar. These payments may be higher than the payments that would be required if this purchase was a non-promo purchase. During the last month(s) of the promo period the required monthly payment may be reduced due to the prior months’ rounding. Regular account terms apply to non-promo purchases. New Accounts as of 07/31/2025: Purchase APR is 34.99%. Penalty APR is 39.99%. Min Interest Charge is $2. Existing cardholders: See your credit card agreement terms. Subject to credit approval.

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off. If you have other balances on your account, this payment will be added to any other minimum monthly payments.
