ALTI (Audio & Loudspeaker Technologies International) has issued a “Call for Content” for ALTI-EXPO 2021. The goal of content presentations is to present new, cutting edge information and education focusing on technical, business, marketing, and general education related to the audio signal chain and all related technologies.

ALTI-EXPO 2021 (AE 2021) will return to DoubleTree by Hilton at Universal Orlando, Florida on October 24 & 25, 2021. The industry has grown accustomed to a world class presentation program at our events, and we need your help to deliver again in 2021. ALTI-EXPO seeks to provide a vibrant and interactive forum to discuss current and future

innovation, as well as the opportunities throughout the audio world. Presentations may be related to Business, Technical, or Education content, however ALTI will consider any content that we believe will be useful to our attendees. Anyone with professional or academic background and knowledge may apply to present including students and educators. Papers,

Advertorials, Seminars, Demonstrations and Exhibits may cover a wide range of products, services, and topics, as long as it relates to the business or technology of the audio industry.

¨ Papers: 20 minutes or less in length. Presentations of academic nature and not self, corporate, or product related.

¨ Advertorials: 20 minutes or less in length. Advertorials will be at no charge for exhibitors. NEW: Non-Members may also present for a $500 fee in addition to your All Access Pass purchase.

¨ Seminars: May be from 1 to 4 hours. Presentations of purely educational value and no commercial promotion.

¨ Speaker Builders Workshop (SBW): Building on the success of our first SBW in 2019, AE 2021 will grow and expand the concept. Please see the  SBW Call for Content to be issued separately.

As a “Thank-you” to our valued Member Presenters*, we offer a FREE 1 day All Access Pass the day of your session as well as breakfast and lunch. If you care to attend both days of the show, Papers or Seminar presenters may purchase a discounted All Access Pass for $199.     *Banquet attendance is $120 extra.

Micro speakers, wireless phones, headphone technology. Testing & production. System design. End of Line testing. New technologies. Of special note; The Speaker Builders Workshop (SBW) was a big hit at AISE2019. Attendees were excited and engaged because of the hands-on aspect of the event. Consider a hands-on presentation for maximum attendee engagement.

¨ All submissions will be considered by our AE 2021 Committee on the basis of their overall quality, relevance and value to the industry, original content, and practical feasibility and usage of topic and information presented.

¨ ALTI will consider all submissions, however ALTI Members will receive priority consideration.

¨ ALTI tries to accommodate all valid submissions, however every year we are forced to decline several excellent presentations because of late submission, and no presentation space left. First come, first served.
