Unity supports importing a variety of source format sound files. However, when importing the sound files (except tracker files), they’re always re-encoded to the build target format. By default, these files are in Vorbis format, but you can override them to other formats (such as ADPCM, MP3) for each platform, if required. Vorbis playback provides better compressionA method of storing data that reduces the amount of storage space it requires. See Texture Compression, Animation Compression, Audio Compression, Build Compression.
See in Glossary and quality for iOS compared to MP3 playback.
Unity iOS doesn’t support DXT textures. Instead, iPhone/iPad devices natively supports ASTC, PVRTC, ETC2, and ETC texture compression3D Graphics hardware requires Textures to be compressed in specialized formats which are optimized for fast Texture sampling. More info
