Seamless M4T audio input sample rate

[tonyv]

I'm using the code provided by HuggingFace for Seamless M4T v1 to do translation for some audio files I have extracted from mp4 video recordings using ffmpeg (cmd used below for reference).

ffmpeg video_recording.mp4 -vn -acodec pcm_s16le -t 30 video_recording_0%d.wav

My understanding is that Seamless M4T v1 was trained on 16K audio . I had a couple of questions.

1. If the audio files I am providing have an original sample rate of 48K and the code resamples it to 16K, would that throw off the translations?

2. If Seamless was trained on 16K audio, can I pass it 48K audio or would that provide suboptimal translations?

3. Can seamless output the intermediate transcription of the audio before it performs the translation?
