Looking for the best listening experience for your iTunes Library? Look no further than LouderLogic – the Advanced Audio Player. LouderLogic features include: - Professional audio enhancement with patented ALX technology - 4-band parametric EQ with Spectrum Animation - Dynamic interactive Play Queues - Crossfading LouderLogic brings the fullness you crave out of every song, using patented Audio Level eXtension (ALX) technology by McDSP. LouderLogic minimizes volume fluctuations between songs while maximizing all the musical details the artist intended you to enjoy. Simply put, you’ll get more from your music! With the McDSP 4-band parametric equalizer, you get the highest quality interactive EQ for your iOS device, along with the ability to customize and tweak to your heart's content. Easily drag the curves to control boost and cut, and use two fingers to adjust the Q (bandwidth).  Spectrum Animation shows you what your music 'looks like' so you can EQ like a pro. Play Queues let you modify what's coming up next at any time, without interrupting your current track. Adjust the crossfade time between songs from 1 to 30 seconds. “If you don’t have LouderLogic I don’t know why you’re even listening to music.” – Chaka Blackmon, Producer/Songwriter for Christina Aguilera, CeCe Winans, MTV and Disney. “LouderLogic is perhaps the most impressive audio enhancement app I have used.” – Kit Eaton, New York Times. Please note that while LouderLogic does play back DRM protected music, it cannot apply ALX enhancement to DRM protected audio. ALX enhancements cannot be applied to music that is still "in the cloud" in iTunes Match, but can be applied once downloaded to your device. Requires iOS 8.0+

BFM or Big F*ing Meters is a macOS, Windows, and soon to be iOS compatible Metering plug-in designed exactly how the name sounds... really f*ing big. With the main goal of readability we wanted to bring a meter that you can see from across the studio and keep your records clip-free. BFM currently offers 6 Modes with RMS, LUFs, Peak, and Peak Hold values, to give you a variety of views to keep your signal under control. The Text, Bars, Waves, VU Meters, Spectrum, & Time  let you decide how you want to keep track of your signal with multiple fonts/formats to view them in. Text gives you a quick look at just the values easy to see from across the room. This view offers the most values with RMS, Peak, Peak Hold, and LUFs (Short Term & Momentary with Maximum values and LUFS range) values available. Controllable sensitivity & peak hold time for all pages. Reset Peak Hold with a click off the value. Bar offers a more traditional meter for seeing the range of values showing RMS, Peak, Peak Hold, and LUFS. Correlation & Balance meters included to set your stereo image and phase response. Peak Hold resets on value click. Sensitivity changes on bar click. LUFS readings select on click. Included reference points for -24 (EBU), -16 (Apple Music), & -7 as a suggested maximum for most genres. Wave view gives you a look at your waveform after your channel effects with the ability to quickly mark in dB where you want to see your signals peak. To freeze click the waveform. To reset Peak Hold click the value. VU Meter Designed for a quick look at your overall levels. Featuring controllable Attack, Release, Minimum, and Maximum value control.
