LTX2.3 3.5 Kit | Avatar Opening · Single Digital Population Singing Audio Driver

This is an AI digital human singing application based on LTX 2.3, IC LipDub, audio-driven, single-person avatar reference, and third-order HD rendering.

Users only need to upload a single-person avatar or character reference image, along with a segment of voiceover, singing, or dubbing audio. The system will generate a digital human performance video based on the audio rhythm and provided prompts.

Unlike ordinary moving avatars, this process incorporates an audio-driven pipeline. The system will process the uploaded audio by separating vocals, trimming the audio, calculating the audio duration, and performing latent audio encoding. Combined with IC LipDub mouth movement guidance, the character can naturally open their mouth, speak, or sing according to the audio.

The entire process is automated: avatar image reading, audio uploading, vocal separation, audio trimming, audio duration calculation, video frame matching, global prompt reading, segmented performance prompt reading, reverse prompt constraints, first-order mouth movement generation, second-order latent space amplification, third-order HD refinement, similarity retention, tail frame trimming, audio reintegration, and final MP4 output.

The final output is a digital human video featuring the original audio, a character's identity that remains as stable as possible, mouth movements synchronized to the audio rhythm, and visuals enhanced through third-order rendering.

It is suitable for applications such as digital human voiceovers, avatar singing, AI virtual hosts, character dubbing videos, single-character performances, virtual IP promotion, short video voiceover materials, song performances, advertisement character videos, and RunningHub video-related application packaging.

If packaged as a RunningHub application, the core selling point can be directly expressed as:

Upload an avatar and an audio clip, and generate a third-order HD digital human video that can talk and sing with one click.
