The differences are as follows:

1. These three are lossless audio file formats. The files of ape and flac are smaller in size than WAV, but they are also lossy. However, the loss is very small and can be ignored, and it is also convenient to convert to WAV. WAV is an earlier computer audio format and is a digital lossless audio.

2. DFF is a DSD encoding audio format jointly developed by Sony and Philips. Its encoding, sampling and other methods are different from the first three, and even the bit depth is different from WAV. Because it has only 1 bit, even so, the file size of dff is larger than that of WAV. The dff two-channel audio is not compressed, the multi-channel audio is compressed, and the file suffix is ??dst.

3. DFF was originally used by Sony for audio on PS game consoles. Later it was derived from SACD, which is Super audio CD. Super audio CD is highly praised by audiophiles because of its better sound quality. In addition to traditional audio manufacturing In addition to commercial players’ players with SACD playback function, some sound card manufacturers currently also include SACD decoding in their sound card products. There are also many players that can play SACD audio in dff format. For computers that do not have hardware to decode SACD, you can use these to play it. Device to soft solution.

Extended information

APE is one of the popular digital music file formats. APE is a lossless compression audio technology, which means that after you compress the audio data files read from the audio CD into APE format, you can also restore the APE format files, and the restored audio files are the same as the compressed audio files. It's exactly the same as before, no loss.

FLAC is the abbreviation of Free Lossless Audio Codec, which can be interpreted as lossless audio compression coding in Chinese. FLAC is a well-known set of free audio compression codes, which is characterized by lossless compression. Unlike other lossy compression codes such as MP3 and AAC, it does not destroy any original audio information, so it can restore the sound quality of music CDs. It has been supported by many software and hardware audio products since 2012.

The WAV format is a sound file format developed by Microsoft, also called a waveform sound file. It is the earliest digital audio format and is widely supported by Windows platforms and their applications.
