The WAV file I created with Protools makes an odd noise each time it starts up.

WAV files created with Protools as well as with certain types of audio software are not standard WAV files. These are WAV Broadcast files which contain ‘metadata’ as well as the standard audio data. The player plays the ‘metadata’ zones in the same way as the audio data, which causes an odd noise at the start of the file reading. To resolve this problem, you can make your WAV files conform by taking out all ‘metadata’ so that only audio data useful to the player is kept. If you do not possess the necessary audio editor to carry out this operation, you can make a copy of your audio file using the software Audacity. This software is under a GPL licence and is free to use whatever your operating system (Windows, Mac OS X or Linux)

Some MP3 files are not correctly play by my player.

At first make sure that the audio file characteristics are same as the specifications of your player (bit rate, number of channels, resolution, encoding types). If everything looks correct, make sure that all metadata (TAG ID3v1 and ID3v2) of your MP3 file is deleted to keep only useful audio data. Some types of TAGs can prevent to playing the file. There are many utilities to manage and remove tags of your files, but if you do not have a reference application, you can use Winamp (Windows) software.

I carefully followed the instructions to naming files and folders explained in the manual but the files and folders do not seem to follow the desired logic.

The problem probably comes from the names of files and folders that you used. Names of files and folders use three characters, neither more nor less. Each character must make a sense according to the user manual and be entered in uppercase. Otherwise, the player apply the default function.

Can I use a Mac OS X system to prepare the contents of my SD card?

You can either prepare your content on MAC OS X, Windows or Linux. All these systems are fully supports the FAT32. However when using a Mac OS, thecopying of files create a number of hidden system (. DS_Store, etc.) files. These files can interfere with the proper operation of your player. This is why it is highly recommended to remove them. Many utilities for Mac lets you remove these unwanted system files such as: Hidden Cleaner, CleanUp smb mess, DS_StoreCleaner or Onyx.

I don't know how my file is encoded. Which software can i use to know precisely which are the caracteristics of my file? (format, type, encoding, bitrate...)

If you have not any software for this, you can use MediaInfo software (http://mediaarea.net/fr/MediaInfo). This software, provided under BSD license, is free and opensource on all operating system (Windows, Mac OS X or Linux).

I hear drop in the sound when I read some MP3 files. What is the problem?

When you use a audio player of the "NanoPlayer" range, your MP3 files must not be encoded more than 128 kbps. This is sufficient in the large majority of uses. It is not recommended to use files encoded at 192kbps, 256 kbps or 320 kbps. If you need a higher quality 128 kbps, use the WAV format instead of the MP3 format.
