Ask Len: how we keep knowledge about sound always within reach

With a knowledge base of 75 questions and an AI assistant that answers day and night, we share what we explain in the studio every day. That way, knowledge about sound is always within reach, even when the studio is quiet.

The same questions keep coming back in the studio. What is the difference between sound design and Foley? Can you use this track in an online campaign? What does a buy-out mean for your voice-over? These are not small questions. Behind each of them is a choice that determines how a brand sounds and what it costs to get it right.

Anyone sitting at our table gets that answer straight away. With headphones on and the sound to go with it. But not everyone is at the table. And questions do not keep office hours.

That is why we built two things: a knowledge base with the questions we get most often and Len, our AI assistant.

A knowledge base of 75 questions

Our Frequently asked questions page has 75 questions and answers, divided into eight themes:

• Audio post-production and sound design
• Sonic branding
• Voice-overs
• AI voices
• Dolby Atmos
• Music production
• Music rights
• Commercial production

Every answer has its own page. Short where possible, detailed where needed. You can read what a 7.1.4 setup is, what synchronization rights are and why a sonic logo is more than a few notes at the end of a spot.

Some answers clear up misconceptions. Take the term royalty-free music. It is used everywhere, but is almost never accurate. Music is only truly free of rights when its copyright has expired. In the Netherlands that is seventy years after the composer's death. And even then the recording itself may still be protected. Find that out too late and you pay the bill afterwards. On our page about music rights and licensing you can read how we arrange that in advance.

Knowledge you share gets better

At TFA we believe craftsmanship does not grow by shielding it. A client who understands what a good mix does listens to the result differently. They hear the space around a voice. They notice that a brand sound is just as recognizable in the third spot as in the first.

That is why we write the answers the way we talk in the studio. Without jargon where it is not needed. With a reference to real work where that helps, such as the World Cup 2026 campaign for Voetbal International or the collaboration between Lidl and TeamNL. An explanation is good. An example you can listen to is better.

Meet Len

A knowledge base answers the questions you already knew. But the best questions are often the ones that have not taken shape yet. That is what Len is for.

Len is TFA's AI assistant. The name is no coincidence. Len knows all the answers from the knowledge base and knows more about audio post-production, sonic branding, voice-overs, AI voices, Dolby Atmos and music rights. You ask your question in plain language and get an answer straight away. Even at eleven at night. Even on a Sunday.

Len does more than give definitions. If you have a project in mind, Len thinks along about the approach and shows which TFA service fits it. That way you come to our table well prepared. With a sharper question and often a direction already.

How it works

1. Go to tfa.studio/en/len or click Ask Len on the frequently asked questions page.
2. Ask your question the way you would ask a colleague. About a term, a rights issue or a project you have in mind.
3. Want to talk further with someone from the team? Then email or call us. Len will show you the way.

Technology as a condition, people as the measure

We have been working with AI voices for years. Always with human direction and only with the explicit consent of the owner of a voice. With Len we apply the same principle. The technology makes knowledge reachable faster. The content comes from more than fifty years of working with sound.

So Len does not replace a conversation. Len makes the conversation better. The same idea is behind SpotFlow, our seven-step briefing process: what is well prepared sounds better.

Sound starts with understanding

Sound has to be heard. No knowledge base changes that. But anyone who understands what they hear makes better choices. About a voice, a track or a mix that will still be right five years from now.

That is what we stand for at TFA. Not just delivering the sound, but also the knowledge behind it.
