XTRAX STEMS: Tips and Tricks

So you have just purchased your own copy of XTRAX STEMS, the world’s first automatic stem creator. Now what? Here are few tips and tricks that can be used in XTRAX STEMS.

Choose a song that will be ideal for remixing or sampling. Many users of XTRAX STEMS intend to isolate the vocals of a song and use the newly created a capella stem for remixing. However, if there are no vocals in the selected song you use in XTRAX STEMS, you will still be able to create a drum stem. Because of this, you can also run separations on instrumental songs as long as there are drum elements present. An example of a song that wouldn’t be ideal for remixing would have only piano, bass, and synth because all three instruments would be categorized as the music stem. Import your song by dragging and dropping it into the XTRAX STEMS playlist or use the import command (ctrl+I / command+I).

person playing the drumsTry running multiple extractions simultaneously to save time. XTRAX STEMS allows for up to four different songs to process at the same time. To do this simply open four separate windows of XTRAX STEMS. This will reduce your wait time if you need to separate more than one song.

Compare your results with the different Algorithms. Process your song with the Automatic, Automatic HQ, Generic, and Generic HQ Algorithms and listen to all of your results to determine which is best for your needs. When selecting the Automatic separation option, the vocal separation occurs using an Automatic Voice Activity Detection process. Vocals are separated only when detected. This algorithm is recommended as a good starting point, as it is more likely to discern and separate only the vocals compared to the Generic options. With the Generic algorithm, the Vocals stem will be made of the main melodic content extracted on the entire duration of the file. It can be useful when the automatic voice activity detection misses segments of the voice, or when trying to extract a monophonic and melodic instrument, such as a saxophone solo.  Use the Solo/Mute buttons to listen to each stem or listen to a pair of stems together.

Save your project with ctrl+s / command+S after you run a separation, if you need to return to the project.

Export your stems into an outside Digital Audio Workstation (DAW). Adjustments can be made to the panning and volume parameters inside of XTRAX STEMS, but these will only get you so far. Once the stems are exported (ctrl+E / command + E) and imported into a DAW, you will be able to adjust the stereo separation and add as many effects as desired. Adding a reverb effect to the vocal stem inside of a DAW will help smooth out the vocals to create a more usable stem. You can also edit out instances of unwanted bleed. 

Separate 2 Create! The beauty of XTRAX STEMS is that you can use the separated stems to independently adjust levels or take it to another level and create an entirely new version of the original song. Add your own samples and remix the song and create something unique. Create a mashup by using another song in the same key/tempo. With each element available independently, you can also export in the NI Stems format to mix with the TRAKTOR CONTROL series of controllers. The opportunities are endless with XTRAX STEMS!

Watch IDC: Instant Dialogue Cleaner Fix Production Dialogue Issues

Audionamix is excited to announce its first real-time product, IDC: Instant Dialogue Cleaner plug-in. Supporting VST and AAX formats, IDC is able to reduce background noise down to -24 db with the turn of a knob. IDC works locally, with minimal processing time, and there is no need for an internet connection. This will be an essential tool for dialogue editors and mixers in reducing a variety of unwanted noise during production recording such as hissing, buzzing, humming, wind, airplanes, refrigerators, and cars. IDC works by using ADX Technology to focus on speech, rather than the traditional approach of other plug-ins that focus on noise. The Algorithms used in ADX Technology are developed using machine learning and a constantly expanding database of speech files.

Through the development of previous Audionamix software such as the TRAX series of products, Audionamix developers wanted to introduce something that would be easy to use for beginners yet powerful enough for professionals. Below are two videos demonstrating the simple and effective noise reducing capability of IDC. A variety of problematic dialogue recordings are used as examples to show the versatility of IDC. IDC will prove to be a valuable plugin for those who need to quickly cleanup dialogue tracks without the headache of processing in an outside program. We are currently testing IDC on a variety of Digital Audio Workstations to ensure maximum compatibility across multiple platforms that offer third party plug-in support. Stay tuned for more announcements regarding IDC!

“Audionamix is the only one that impressed me. This technology is amazing” – Joachim Garraud

Here in our Paris office, our French Research and Development team had the chance to welcome the one and only Joachim Garraud. He came for a Facebook Live event, and it was a pure pleasure to meet him. Telma, our Deputy-CEO, began the event by talking about the history of Audionamix. She discussed the projects we did with Hans Zimmer on Inception and our work with Canal+ on the World Cup 2010.

Next, one of our audio engineers showcased how he uses his skills at Audionamix with an amazing demo. Working all day with Pro Tools, Ableton Live and other DAWs is a fantastic way to make a living! Then we featured a little of our core audio source separation technology, and discussed how our researchers use signal processing, machine learning, deep learning and some other dark magic.

The last part of this FB Live featured another one of our engineers, Laurent, and was focused on how we handle product development. Laurent showcased the utility of our brand new software, XTRAX STEMS, with NI Traktor. Laurent performed a live remix, featuring our software.  Also, Laurent gave Joachim a little surprise that you can see by watching the FB Live yourself!

As you will see, it was a fantastic experience for all of us to welcome Joachim Garraud in our office. We hope you enjoy it as much as we did!

Cheers from France!

Love, music and macarons!

Separation Stories

Jay Graydon and Bill Evans talk TRAX Pro and remastering Airplay

 

Musicians and audio engineers around the world use Audionamix software every day to create, remix, and restore. Recently, Grammy-winner Jay Graydon and engineer extraordinaire Bill Evans used TRAX Pro to help in the remastering of a classic album.

Jay Graydon laying down tracks in the studio

Jay Graydon on how TRAX Pro helped solve a remastering challenge:

David Foster and I are Airplay, and recorded an album by the same name in 1979. It went Gold in Japan and continues to sell well around the world. The record company recently asked that I remaster the mixes for an upcoming re-release, but there was a problem: the vocals needed remixing…and the multi-tracks weren’t accessible.

The song, “Stranded” needed the most help. On the stereo mix, I’d added major EQ in the low frequency area (120 shelf) as well as rolling out EQ at 2.5 k area. But this left the vocals too low! So, I asked Bill if it would be possible to extract the vocals from the mix.

Tom [Price] and Bill worked on it, and I received the finished audio of the instrument track along with three vocal tracks. When playing the music and the vocal tracks together, it matched perfectly with the original. BUT then it was time to hear what happens when bringing up the vocal level…I brought up the vocal level between 1 to 3 dB using automation in Pro Tools and I WAS AMAZED…IT SOUNDED PERFECT, MEANING NO ARTIFACTS WERE HEARD!!!!

 

The full story of the re-mastering of Airplay (with audio examples of the before and after for the song “Stranded”) will be posted on my website (www.jaygraydon.com), as well as where to get the re-mastered version of Airplay [to be released by SONY].

Bill Evans on using TRAX Pro for creating the vocal separation tracks:

When Jay asked me about doing this, I was intrigued and a little nervous—Jay is renowned for having some of the best ears in the business. Not to mention David Foster. And I had no idea how to separate multiple vocal tracks to the degree he needed…no one I spoke to had heard of it being done. But I figured if anything could handle the heavy lifting, it was Audionamix tech.

I spoke to Steve Oliver at Audionamix, who was kind enough to discuss their technical approach to the problem. I was hooked, and we dove in. Jay created MIDI guide files for the vocal melodies, and my assistant Tom used TRAX Pro to produce the three separate vocal separation tracks, as well as the instrumental tracks. He (and TRAX Pro) did an amazing job, and TRAX’s post-processing tools helped further improve the results (particularly in removing high-end drum bleed that coincided with vocal consonants).

If there was only one vocal track, we’d have been finished. But the three vocal tracks still needed to reassemble, simultaneously, without frequency cancellation. So Tom used a spectral editor (SpectraLayers) for post-processing on the frequency overlaps, and the project was complete.

It was a privilege to work with Jay Graydon, and I look forward to working with him (and TRAX Pro) in the future!

On Tuesday, Audionamix’s own Audio Engineer Doc Vaporz dropped by the home-studio of Artist Joachim Garraud for a wildly successful Facebook Live stream, featuring Joachim’s remixing work using XTRAX STEMS.

Joachim said that he has been waiting 12 years to find software that does what XTRAX STEMS does!

 

During the session, Joachim showcased the power of XTRAX STEMS on some classic tracks:

“Jammin” by Bob Marley
“The Wall” by Pink Floyd
“I Got You, Babe” by UB40

 

Doc and the Facebook Live audience were treated to a bilingual demonstration of Joachim’s thought process and workflow when using separated stems from XTRAX STEMS to create original works in Ableton Live.

Over 400 international participants wrote in, and Joachim and Doc answered as many questions as they could.

•”Is it better to start with a .wav file than an .mp3?”   Yes

•”Is it possible to export in a TRAKTOR Stems file?”   Yes

•”Is it possible to manually get higher refinement?”   If you work in our pro line product TRAX Pro, then you can get the best of both worlds – the drum separation in XTRAX STEMS and the refinement tools of TRAX Pro.

•”Is it available for both Mac and Windows?”   As of today, Yes. XTRAX STEMS for Windows is now available for presale at the introductory price of $79. It will retail upon release at $99. Existing Mac versions will become cross platform compatible upon the release.

Joachim gave away of one copy of XTRAX STEMS, and the lucky winner was Victor Carré – CONGRATULATIONS!

Joachim has been a huge supporter of XTRAX STEMS, and we are looking forward to additional Facebook Lives with him in the future, so stay tuned…and you can watch yesterday’s video here.

Venomisto Presents ADX TRAX Pro 3 SP Tutorial Series

Hi all,

I’m excited to be working together with Audionamix on some real cutting edge technology. Their source separation solution is the only one I’ve found that really works for creating professional sounding acapellas and instrumentals.

I’ve gone ahead and put together a 5-part video tutorial series on using Audionamix ADX TRAX Pro 3 SP to isolate vocals from a song. In it, we’ll walk through a vocal extraction together, from start-to-finish. Some of the things we’ll cover include:

  • Running the initial audio source separation
  • Refining the pitch guide to achieve a more accurately pitched separation
  • Boosting consonants to extract those hard-to-isolate “S” and “F” sounds
  • Using different algorithms to get the best end result possible
  • Diving into the Spectral Editor to polish your isolation for that last 5–10%

CLICK HERE TO WATCH THE VOCAL EXTRACTION TUTORIAL SERIES

In addition to this tutorial series, I’ve been doing Pro Tip videos. In these, I explain how to use a TRAX power feature. You can find the first 2 I did here, where we cover the Smart Attenuate Tool and the Pan-Specific View.

Finally, I’ll also be live streaming my production process for a new remix track, using TRAX to get the original acapella. I’m pretty excited about it, so stay tuned for more!

Check out the tutorial series today, be sure to subscribe if you enjoy it, and of course, leave a comment if you have any questions or ideas for more videos you’d like to see.

Until next time,
