I have a 1hr 33m WAV file which is a recording of a church service. I converted it to MP3 using PolderbitS Sound Editor. The file sizes are 473MB (WAV) and 32MB (MP3).
The files are located on a USB HDD connected to the TV directly via one of its USB ports.
When I run the Media Player and select Music and Folder view, only the MP3 file is displayed, and when I select it, the play length is recognised but the file doesn't play. The Play symbol changes to a Pause symbol, but the play position doesn't change from 0:00:00.
According to the manual, MP3 is supported, along with AAC, WMA, WMA Pro & FLAC.

Any help would be appreciated.

Those numbers seem a lot off for a stereo WAV. And rather low for MP3.


As a rule of thumb a stereo WAV is about 10.5 MB/minute. While MP3 at 128kbit/s is about 1MB/minute.

---------------------------------
If the WAV is mono then I suppose it's close to being correct.

So is the WAV mono? And is the MP3 also mono? (at 48kbit/s by my calculation)

Maybe the TV cannot play mono MP3?

-------------------
If the MP3 is in stereo then maybe the "sampling rate" is not supported by the TV. I say this because a stereo MP3 at such a low bit rate must have been encoded with a very low sampling rate.

The sampling rate is the numbers 32kHz or 44.1kHz or 48kHz

You need to find out what the MP3 is encoded too. Play it on a PC/Laptop and find out what the details are of this MP3 you have encoded.

How was the recording done in the first place, what device?

The WAV might be weirdly non standard.

The MP3 has a bit rate of 48kbps, while the WAV has a bit rate of 705kbps. PolderbitS Sound Recorder has a few quality settings and this recording is made to WAV using the "FM Stereo" setting. It is a 2-channel recording, which we would mix to mono but this is the raw file. The WAV and MP3 both play in Windows Media Player.
The recording is made via a USB soundcard called an i-Mic.

I would try and re-encode the MP3 at a much higher bit-rate, like 128kbps

Try and ensure the "sampling rate" is at 44.1kHz.
