MPEG-1 Audio Layer 1 (MP1) is an earlier, simpler version of the MPEG audio standard. MP1 is mostly obsolete, but still supported. MP1 was part of the Digital Compact Cassette format. Almost all files that were MP1 were replaced by the newer MPEG-1 Audio Layer II (MP2) and MPEG-1 Audio Layer III or MPEG-2 Audio Layer III (MP3) file formats.
Due to MP1 being largely obsolete, VLC media player is the best option for opening an MP1 file, with the bonus that this player works across platforms.

Adaptive Multi-Rate (AMR) is a compressed audio file that is often used for speech coding. The AMR speech codec focuses on narrowband signals, which makes it ideal for voice recordings and radio. It is used regularly in Global System for Mobile Communications (GSM) and Universal Mobile Telecommunications System (UMTS).
Other software, such as the free audio-editing software Audacity, can open AMR files. Download audacity easily at SourceForge.net. Because AMR files are heavily compressed and focused on narrowband signals, they are not suitable for music files.
