Features Users Want Most in Mastering Assistant Apps

"We need to be able to export mastered audio in a .wav in order to protect the audio quality, but all I've gotten was .mp3."

"There is no compressor, limiter, etc. There is only an equalizer"

"Offers a small set of fixed presets with no visibility into or control over core mastering parameters such as EQ, compression, limiting, loudness, or stereo width."

"a trim function would be great. It comes in in the middle of the first beat and that's not good."

"Is there any video or website to learn this app properly, I feel like GarageBand is much better than this and free."

"How does it make the loudness go up"

Build mastering tool with fully interactive, real-time parameter controls

29% of complaints stem from deceptive static UI. Users expect and will pay for genuine control over EQ, compression, limiting, and stereo width with visible values and adjustments.

Single transparent pricing tier with WAV export included

21% of complaints about double-dipping monetization. Offer $29.99-$39.99 one-time purchase with all features unlocked, including lossless export, to build trust and avoid refund rage.

Implement visual feedback for all processing (meters, waveforms, spectrum)

Users need to see what's happening to their audio. Real-time visualization of compression, EQ curves, loudness metering will differentiate from broken competitors and build professional credibility.

Include in-app tutorials and preset explanations

Users are comparing to GarageBand and don't understand the value proposition. Contextual help explaining what each preset does and why will justify premium pricing and reduce support burden.

Guarantee stability with robust import/export testing

17% encounter crashes or complete non-functionality. Rock-solid reliability with multiple format support (WAV, MP3, AAC, FLAC) and AUv3 compatibility will capture users fleeing broken alternatives.
