NUGEN Audio MasterCheck 2: Loudness and Codec Preview

NUGEN Audio MasterCheck 2 is a metering and auditioning plug-in that shows exactly how your master will sound once a streaming platform has normalised and compressed it. It measures loudness and true peak to broadcast standard, then previews the effect of MP3, AAC, Ogg, FLAC and Opus codecs in real time, so you hear the delivered result before you export. It now covers surround up to 7.1.4 and immersive audio. Mac and Windows, in one purchase.

What’s Inside NUGEN Audio MasterCheck 2

• Loudness metering: integrated, short-term and momentary loudness plus loudness range, PLR and PSR for streaming compliance to broadcast standard.
• True peak metering: ITU-compliant inter-sample peak metering to stop codec clipping before it happens.
• Codec preview: hear MP3, AAC, Ogg, FLAC and Opus in real time from inside the session, no exporting and testing.
• Streaming presets: targets for Spotify, Apple Music, YouTube, TIDAL, Bandcamp, SoundCloud and more.
• Immersive support: metering and codec preview up to 7.1.4 for surround and Dolby Atmos delivery.
• Resizable interface: a redesigned portrait or landscape layout that fits any screen.

Who Is NUGEN Audio MasterCheck 2 For?

Mastering engineers get the most from this loudness meter, because it shows the delivered sound each platform will actually play rather than the raw file. Producers who release to streaming use it to stop their tracks being turned down or crunched by a codec. Podcast and broadcast engineers use it to hit strict delivery specs. Anyone working in surround or Dolby Atmos gets the same checks across immersive formats.

How Producers Use NUGEN Audio MasterCheck 2

A mastering engineer puts this loudness meter last on the master, loads the Spotify preset and pushes the limiter until the integrated loudness sits at the target while the true peak stays below the codec-safe ceiling. Then they switch on the AAC preview and listen to what streaming will actually deliver, catching distortion the raw file never showed, much as they would confirm the numbers against a metering tool from the mastering plugins shelf. Electronic producers compare the same master across the YouTube and Apple Music presets so it holds up wherever it lands. Because it previews the codec in real time, there is no bounce-and-check loop.

Questions Producers Ask

What does NUGEN MasterCheck 2 do?

It meters loudness and true peak to broadcast standard and previews how streaming codecs will change your master. You hear MP3, AAC, Ogg, FLAC or Opus processing in real time and check the loudness against presets for Spotify, Apple Music, YouTube and more, so you know the delivered sound before you export the file.

Does MasterCheck preview streaming codecs?

Yes, that is its signature feature. Instead of bouncing a file and uploading it to test, you monitor the codec effect live inside the session. MasterCheck 2 covers MP3, AAC, Ogg, FLAC and Opus, and it shows how each platform’s loudness normalisation will turn your master up or down as you master for streaming, so nothing surprises you after release.

Does MasterCheck 2 support surround and Dolby Atmos?

Yes. Version 2 extends the loudness metering and codec preview up to 7.1.4 channels, so it works for immersive music, film, broadcast and gaming as well as stereo streaming. That makes it a single tool for checking delivery across both traditional and immersive formats.
