Far More Than a Meter

Get to know them!

At Sweetwater, we know that metering is serious business — it shouldn't be an afterthought. Luckily, Waves feels the same way, and has given us a comprehensive loudness meter plug-in that delivers precision loudness measurement, metering, correction and adjustment tools for whatever aspect of audio production you're into, be it music production, broadcast, movie trailers, or games. WLM Plus serves up momentary, short term, long term, and true peak readouts, as well as a cool warning and logging system that keeps track of your levels, alerting you when you've exceeded them — or fallen short. You also get Gain and Trim controls, plus a True Peak Limiter — which means WLM Plus is far more than a meter.

Waves WLM Plus Loudness Meter Features at a Glance:

  • ITU 1770-3, EBU and ATSC compliantForeground, dialog, and average loudness measurements
  • Momentary, Short Term and Long Term readouts
  • Gain and Trim controls for loudness normalization and correction
  • True Peak meter and True Peak limiter
  • Mono, stereo, and 5.0, 5.1 components

Offer applies only to single-receipt qualifying purchases. Select manufacturers may require that only the manufacturer’s products qualify towards the minimum purchase amount needed to be eligible for promotional financing. 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.

Offer applies only to single-receipt qualifying purchases. No interest will be charged on the promo balance if you pay it off, in full, within the promo period. If you do not, interest will be charged on the promo balance from the purchase date. The required minimum monthly payments may or may not pay off the promo balance before the end of the promo period, depending on purchase amount, promo length and payment allocation. Regular account terms apply to non-promo purchases and, after promo period ends, to the promo balance. 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.
